-### About the source codes (in BSV and Verilog)
-
-The BSV source code in this repository, from which the synthesizable
-Verilog RTL in this repository is generated, is highly parameterized
-to allow generating many possible configurations, some of which are
-adequate to boot a Linux kernel.
-
-The pre-generated synthesizable Verilog RTL source files in this
-repository are for a few specific configurations:
-
-1. RV32ACIMU:    **(DARPA SSITH users: this is the "P1" processor)**
-    - RV32I: base RV32 integer instructions
-    - 'A' extension: atomic memory ops
-    - 'C' extension: compressed instructions
-    - 'M' extension: integer multiply/divide instructions
-    - Privilege levels M (machine) and U (user)
-    - Supports external, timer, software and non-maskable interrupts
-    - Passes all riscv-isa tests for RV32ACIMU
-    - Boots FreeRTOS
-
-2. RV64ACDFIMSU
-    - RV64I: base RV64 integer instructions
-    - 'A' extension: atomic memory ops
-    - 'C' extension: compressed instructions
-    - 'D' extension: double-precision floating point instructions
-    - 'F' extension: single-precision floating point instructions
-    - 'M' extension: integer multiply/divide instructions
-    - Privilege levels M (machine), S (Supervisor) and U (user)
-    - Supports external, timer, software and non-maskable interrupts
-    - Passes all riscv-isa tests for RV64ACDFIMSU
-    - Boots the Linux kernel
-
-If you want to generate other Verilog variants, you'll need a Bluespec
-`bsc` compiler [Note: Bluespec, Inc. provides free licenses to
-academia and for non-profit research].
-
-The BSV source code supports:
-
-- RV32I or RV64I
-- Optional 'A', 'C', 'D', 'F' and 'M' extensions
-- Privilege level options M, MU and MSU
-- For privilege S, virtual memory schemes Sv32 (RV32) and Sv39 (RV64)
-
-- Hardware implementation option: serial shifter (smaller hardware, slower) or barrel shifter (more HW, faster) for shift instructions
-- Hardware implementation option: serial integer multiplier (smaller hardware, slower) or synthesized (more HW, faster)
-- AXI4-Lite Fabric interfaces, with optional 32-bit or 64-bit datapaths (independent of RV32/RV64 choice)
-- and several other localized options
-
-### Testbench included
-
-This repository contains a simple testbench (a small SoC) with which
-one can run RISC-V binaries in simulation by loading standard mem hex
-files and executing in Bluespec's Bluesim, Verilator simulation or
-iVerilog simulation.  The testbench contains an AXI4-Lite interconnect
-fabric that connects the CPU to models of a boot ROM, a memory, a
-timer and a UART for console I/O.
-
-[Note: **iverilog functionality is currently limited** because we are
-still working out robust mechanisms to import C code, which is used in
-parts of the testbench.]
-
-This repository contains several sample build directories, to build
-RV32ACIMU or RV64ACDFIMSU simulators, using Bluespec Bluesim
-simulation, Verilator Verilog simulation, or Icarus Verilog
-("iverilog") simulation.
-
-The generated Verilog is synthesizable. Bluespec tests all this code
-on Xilinx FPGAs.
-
-#### Plans
-
-- Ongoing continuous micro-architectural improvements for performance and hardware area.
+- [Tooba](https://github.com/bluespec/Tooba): superscalar, out-of-order
+  pipeline, slight variation on MIT's RISCY-OOO [In progress!]
 
 ----------------------------------------------------------------
-## Source codes
+### Note re. distribution of MIT RISCY-OOO sources.
 
-This repository contains two levels of source code: Verilog and BSV.
+The directory `src_Core/RISCY_OOO` contains sources copied from MIT's
+`riscy-OOO` repository.  See `LICENSE_RISCY-OOO` for MIT's license.
 
-**Verilog RTL** can be found in directories with names suffixed in
-'_verilator' or '_iverilog' in the 'builds' directory:
-
-        builds/..._<verilator or iverilog>/Verilog_RTL/
-
-[There is no difference between Verilog in a Verilator directory
-vs. the corresponding iverilog directory. ]
-
-The Verilog RTL is _synthesizable_ (and hence acceptable to
-Verilator).  It can be simulated in any Verilog simulator (we provide
-Makefiles to build simulation executables for Verilator and for Icarus
-Verilog (iverilog)).
-
-The RTL represents RISC-V CPU RTL, plus a rudimentary surrounding SoC
-enabling immediate simulation here, and which is rich enough to enable
-booting a Linux kernel.  Users are free to use the CPU RTL in their
-own Verilog system designs.  The top-level module for the CPU RTL is
-`Verilog_RTL/mkBRVF_Core.v`.  The top-level module for the surrounding
-SoC is `Verilog_RTL/mkTop_HW_Side.v`.  The SoC has an AXI4-Lite
-fabric, a timer, a software-interrupt device, and a UART.  Additional
-library RTL can be found in the directory `src_bsc_lib_RTL`.
-
-**Bluespec BSV** source code (which was used to generate the Verilog RTL) can be found in:
-
-- `src_Core/`, for the CPU core, with sub-directories:
-   - `ISA/`:  generic types/constants/functions for the RISC-V ISA (not CPU-implementation-specific)
-   - `RegFiles/`: generic register files for the GPRs (General-Purpose Registers) and CSRs (Control and Status Registers)
-   - `Core/`: the CPU Core
-   - `Near_Mem_VM/`: for the MMU and first-level cache.  In the CPU,
-        this is instantiated twice to provide completely separate
-        channels (MMU and Cache) for instructions and data.
-   - `BSV_Additional_Libs/`: generic utilities (not CPU-specific)
-   - `Debug_Module/`: RISC-V Debug Module to debug the CPU from GDB or other debuggers
-
-- `src_Testbench/`, for the surrounding testbench, with sub-directories:
-
-   - `Top/`: The system top-level (`Top_HW_Side.bsv`), a memory model
-       that loads from a memory hex file, and some imported C
-       functions for polled reads from the console tty (not currently
-       available for Icarus Verilog).
-
-   - `SoC/`: An interconnect, a boot ROM, a memory controller, a timer
-       and software-interrupt device, and a UART for console tty I/O.
-
-   - `Fabrics/`: Generic AXI4-Lite code for the SoC fabric.
-
-The BSV source code has a rich set of parameters, mentioned above. The
-provided RTL source has been generated from the BSV source
-automatically using Bluespec's `bsc` compiler, with certain particular
-sets of choices for the various parameters.  The generated RTL is not
-parameterized.
-
-To generate Verilog variants with other parameter choices, the user
-will need Bluespec's `bsc` compiler.  See the next section for
-examples of how the build is configured for different ISA features.
-
-In fact the CPU also supports a "Tandem Verifier" that produces an
-instruction-by-instruction trace that can be checked for correctness
-against a RISC-V Golden Reference Model.  Please contact Bluespec,
-Inc. for more information.
+[Note: MIT's repository is on an MIT git server, which can only be
+ accessed with credentials; hence the local copy in of these files.]
 
 ----------------------------------------------------------------
-### Building and running from the Verilog sources, out of the box
+### Building and running Tooba
 
-In any of the Verilog-build directories:
+You will need:
 
-            builds/<ARCH>_<CPU>_verilator/
-            builds/<ARCH>_<CPU>_iverilog/
+- A Bluespec tools installation (so you can run 'bsc', the Bluespec
+  compiler for BSV).  We recommend version 2018.10.beta1 or later.
 
-  - `$ make simulator` will create a Verilog simulation executable using Verilator or iverilog, respectively
+- A Verilator installation.  We recommend version 3.922 or later.
 
-  - `$ make test` will run the executable on the standard RISC-V ISA
-        test `rv32ui-p-add` or `rv64ui-p-add`, which is one of the
-        tests in the `Tests/isa/` directory.  Examining the `test:`
-        target in `Makefile`, we see that it first runs the program
-        `Tests/elf_to_hex/elf_to_hex` on the `rv32ui-p-add` or
-        `rv64ui-p-add` ELF file to create a `Mem.hex` file, and then
-        runs the simulation executable which loads this `Mem.hex` file
-        into its memory.
+Then:
 
-  - Following the pattern of `$ make test`, the user can run any of
-    the other tests in the `Tests/isa/` directory by pointing at the
-    chosen ELF file.
+    $ cd  builds/RV64ADFIMSU_Tuba_verilator
+    $ make all
 
-  - `$ make isa_tests` will run the executable on
-      all the standard RISC-V ISA tests relevant for ARCH (regression testing).
-      This uses the Python script `Tests/Run_regression.py`.
-      Please see the documentation at the top of that program for details.
+This will compile BSV sources using the 'bsc' compiler into Verilog in
+the directory `Verilog_RTL`, then compile and link into a verilator
+executable `exe_HW_sim`.
 
-Note: an RV32ACIMU simulator will only successfully run ELF files
-compiled for RV32ACIMU, privilege U and M; running it on any other ELF
-file will result in illegal instruction traps.  An RV64ACDFIMSU
-simulator will successfully run ELF files compiled for RV64ACDFIMSU,
-privilege U, S and M.
+Then:
 
-#### Tool dependencies:
+    $ make test                                   (1)
+    $ make TEST=<isa_test_name> test              (2)
+    $ make isa_tests                              (3)
 
-We test our builds with the following versions of iVerilog and
-Verilator.  Later versions are probably ok; we have observed some
-problems with earlier versions of both tools.
-
-        $ iverilog -v
-        Icarus Verilog version 10.1 (stable) ()
-
-        $ verilator --version
-        Verilator 3.922 2018-03-17 rev verilator_3_920-32-gdf3d1a4
-
-----------------------------------------------------------------
-### What you can build and run if you have Bluespec's `bsc` compiler
-
-[Note: Bluespec, Inc. provides free licenses to academia and for non-profit research].
-
-Note: even without Bluespec's `bsc` compiler, you can use the Verilog
-sources in any of the `builds/<ARCH>_<CPU>_verilator/Verilog_RTL`
-directories-- build and run Verilog simulations, incorporate the
-Verilog CPU into your own SoC, etc.  This section describes additional
-things you can do with a `bsc` compiler.
-
-#### Building a Bluesim simulator
-
-In any of the following directories:
-
-        builds/<ARCH>_<CPU>_bluesim
-
-  - `$ make compile simulator`
-
-will compile and link a Bluesim executable.  Then, you can `make test`
-or `make isa_tests` as described above to run an individual ISA test
-or run regressions on the full suite of relevant ISA tests.
-
-#### Re-generating Verilog RTL
-
-You can regenerate the Verilog RTL in any of the
-`build/<ARCH>_<CPU>_verilator/` or `build/<ARCH>_<CPU>_iverilog/`
-directories.  Example:
-
-        $ cd  builds/RV32ACIMU_<CPU>_verilator
-        $ make compile
-
-#### Creating a new architecture configuration
-
-In the `builds/` directory, you can create a new sub-directory to
-build a new configuration of interest.  For example:
-
-        $ cd  builds
-	$ Resources/mkBuild_Dir.py  ..  RV32CI  bluesim
-
-will create a new directory: `builds\RV32CIU_<CPU>_bluesim`
-populated with a `Makefile` to compile and link a bluesim simulation
-for an RV32 CPU with 'I' and 'C' ISA options.  You can build and run
-that simulator as usual:
-
-        $ cd  builds/RV32CIU_<CPU>_bluesim
-        $ make compile simulator test isa_tests
+(1) Will run a single ISA test, `rv64ui-p-add`.
+(2) Will do the same, but with the ISA test whose name you supply.
+(3) Will run ISA tests for RV64G.

+>================================================================
+The './isa' sub-directory contains pre-built ELF and objdump files
+(.dump) for all the standard RISC-V ISA tests.  For example, the
+files:
+
+    ./isa/rv32ui-p-add
+    ./isa/rv32ui-p-add.dump
+
+are an ELF file and its objdump (disassembly) that tests the RISC-V
+user-level integer ADD instruction for RV32.  The tests are built when
+one clones the following GitHub repository:
+
+    https://github.com/riscv/riscv-tools.git
+
+and follows the build directions therein, resulting in all the ISA
+tests being built, such as this:
+
+    <riscv-tools build dir>/riscv64-unknown-elf/share/riscv-tests/isa/rv32ui-p-add
+
+>================================================================
+The Makefile has a command to run regressions on ISA tests.
+
+    $ make test
+
+In the Makefile, you will see definitions for ARCH (such as `RV32IMU`)
+and SIM (such as `verilator`), which together specify which simulator
+will be run (`builds/<ARCH>_SIM/exe_HW_sim`).  You can change the ARCH
+and SIM definitions in the Makefile for a different simulator, or
+redefine them on the `make` command line.
+
+It will run the the Python program 'Run_regression.py', described
+below, to run the simulator on all the ISA tests relevant to the
+architecture ARCH.  A per-ISA-test log is captured in the 'Logs/'
+directory.
+
+>================================================================
+With the Python program './Run_regression.py' you can run a regression
+on all the standard RISC-V ISA tests that are relevant to your RISC-V
+simulation executable (i.e., for the RISC-V features and extensions
+supported by your simulation executable).
+
+Please do:
+
+    $ ./Run_regression.py  --help
+
+for usage information.
+
+Example:
+
+    $ ./Run_regression.py  ../RV32IMU_verilator/exe_HW_sim  ./isa  ./Logs  v1
+
+will run the verilator simulation executable on the all RISC-V ISA
+tests that match the following:
+
+    ./isa/rv32ui-p*
+    ./isa/rv32mi-p*
+    ./isa/rv32um-p*
+
+and leave a transcript of each test's simulation output in files like
+    ./Logs/rv32ui-p-add.log
+Each log will contain an instruction trace.
+
+Example:
+
+    $ ./Run_regression.py  ../RV64AIMSU_verilator/exe_HW_sim  ./isa  ./Logs  v1
+
+will run the verilator simulation executable on the all RISC-V ISA

+This standalone C program takes two command-line arguments, and ELF
+filename and a Mem Hex filename.  It reads the ELF file and writes out
+the Mem Hex file.
+
+It assumes a memory that is:
+  - 16 MiB or 256 MiB (see C file)
+  - Each word is 32 bytes (256 bits)
+  - It starts at byte address 0x_8000_0000
+
+All of these can be changed by editing the C file.

+// - carry the data bytes on the lanes corresponding to the byte addresses,
+//     along with a 'mask' indicating which bytes are valid:
+//        Lane:    7 6 5 4 3 2 1 0

+
+// ================================================================
+// This is the top-level package of a collection that implements the
+// "Debug Module" specified in:
+//
+//     "RISC-V External Debug Support"
+//     Version 0.13
+//     7c760b0151e43523ab3d2180e7852cd6f27d942c
+//     Mon Jul 3 17:04:59 2017 -0700
+
+// Note: the spec actually represents three (almost) completely
+// independent functionalities:
+//   Run Control:       to start/stop harts, query their start/stop status, etc.
+//   Abstract Commands: to read/write RISC-V registers and RISC-V CSRs
+//   System Bus Access: to read/write RISC-V memory/devices
+
+// The only exception to complete independence is that the Run Control
+// part has a 'reset' for the Debug Module itself, which includes all
+// three parts.
+
+// Unfortunately the spec is not written to make this three-part
+// organization clear--aspects of the three parts are completely
+// intermingled.  Even the address map mixes registers from the three
+// parts.
+
+// Here, this top-level package is merely a wrapper that dispatches
+// DMI requests to the three packages that implement the three parts:
+//     DM_Run_Control
+//     DM_Abstract_Commands
+//     DM_System_Bus
+
+// DM_Common contains common spec-level (implementation-independent) definitions.
+
+// ================================================================
+// Our Debug Module (DM) has a two sides:
+//   - GDB/Host-facing
+//   - CPU/Platform-facing
+
+// The GDB/Host-facing side is called DMI (Debug Module Interface) in
+// the spec, and is a simple memory-like read/write interface, into a
+// debug module address space (unrelated to the RISC-V memory address
+// space).
+
+// The CPU/Platform-facing side has request/response interfaces for
+// CPU run-control, CPU register/CSR access and RISC-V system memory
+// access.

+'Debug_Module' implements a Debug Module for RISC-V processors in
+accordance with the RISC-V standard "External Debug Support" spec:
+
+    RISC-V External Debug Support
+    Version 0.13-DRAFT
+    dd8d8714184970031fa447a452068223f257b51c
+    Mon Dec 18 13:54:14 2017 -0800
+
+Note: the spec is independent of any particular RISC-V CPU
+implementation.  It just specifies the standard registers in the Debug
+Module that can be read and written by an external debugger (such as
+GDB).  It specifies the address map of these registers, and the
+semantics, i.e., what happens when one reads or writes these
+registers.  The spec does not say anything about how this spec is
+implemented.
+
+Please see comments in Debug_Module.bsv for more details on our
+implementation of the Debug Module spec.  This implementation is also
+not specific to any particular CPU implementation.  We use it in
+Bluespec RISC-V CPUs, but it could be used with other CPUs as well.
+We use this Debug Module in the Bluespec RISC-V Verification Factory
+(BRVF).

+Module based on the spec.

+
+// XXXTransfer is conflict with each other
+// Impl of getEmptyEntry and releaseEntry ensures that they are not on the same entry (e.g. cRqTransfer v.s. sendRsToC)
+// XXXTransfer should operate on different cRq/pRq from other rules
+
+// sendRsToC is ordered after pipelineResp to save 1 cycle in I$ latency
+
+// sendRqToP and sendRsToP_cRq are read only
+
+// sendRsToP_pRq is operating on different pRq from pipelineResp_pRq (since we use CF index FIFO)
+
+// ---- conclusion ----
+
+// rules/methods are operating on different MSHR entries, except pipelineResp v.s. sendRsToC
+
+// we have 5 ports from cRq MSHR
+// 1. cRqTransfer
+// 2. sendRsToC
+// 3. sendRsToP_cRq
+// 4. sendRqToP
+// 5. pipelineResp
+
+// we have 3 ports from pRq MSHR
+// 1. pRqTransfer
+// 2. sendRsToP_pRq
+// 3. pipelineResp
+
+// safe version: use EHR ports
+// sendRsToP_cRq/sendRqToP/pipelineResp < sendRsToC < cRqTransfer
+// pipelineResp < sendRsToP_pRq < pRqTransfer
+// (note there is no bypass path from pipelineResp to sendRsToP_pRq since sendRsToP_pRq only reads pRq)
+
+// unsafe version: all reads read the original reg value, except sendRsToC, which should bypass from pipelineResp
+// all writes are cononicalized. NOTE: writes of sendRsToC should be after pipelineResp
+// we maintain the logical ordering in safe version

+// although pRq never appears in dependency chain
+// we still need pRq MSHR to limit the number of pRq
+// and thus limit the size of rsToPIndexQ
+
+// The "cs" field of cRq MSHR slot is in fact useless, we only need to know if
+// a cRq is wait for parent resp.
+
+// The "fromState" field of req to parent is in fact useless, because parent
+// can judge whether it needs to wait for downgrade from the requesting child
+// based on the directory
+
+// We use the other field of cache info to track the number of hits on a cache
+// line to guarantee forward progress of spin-load. The hit count has the
+// following invariants:
+// - Hit count is 0 in E and M states
+// - Hit count is ? in I state
+// - Hit count is the number of consecutive load hits if state is S
+// We operate the hit count in the following way:
+// - Hit count is incremented when load hits on S state
+// - Hit count is reset to 0 when state is upgraded by parent (I->S, S->E/M)
+// - Hit count does not change when state is downgraded
+
+// XXX Link addr reserved by LR is only valid if the line is in E/M state,
+// because parent does not track S copies. Self-inv only downgrades from S to
+// I, so it won't affect link addr.

+// we use an infoQ to serialize all req to memory
+// this also ensures that cache pipeline is never blocked
+// so we do not need to buffer mem resp that needs to refill cache
+
+// XXX we need to maintain the invariant that 
+// at most 1 pRq sent to a child for an addr
+// and we have to wait for resp before sending anthoer one
+
+// In future, it would be hard to parallelize sendRqToC and pipelineResp
+// because sendRqToC must see updates to dirPend made in pipelineResp
+// or we simply stall sendRqToC
+
+// XXX DMA req are put in the same MSHR as child req
+// this ensures that child req always get a cache line to occupy after being sent to pipeline
+
+// DMA req are handled in the following way
+// (1) If it hits in LLC, then we can downgrade children and process it
+// (2) Otherwise, we req memory, XXX and req is viewed as Done
+//     The dep successor is sent to retry instead of being swapped in,
+//     because we don't have a cache line to occupy...
+//     When the mem resp comes, we send DMA resp and DO NOT fill cache
+
+// XXX mem resp that refill cache are for child req, others that don't refill cache are for DMA req
+
+// XXX Directory should be I (instead of don't care) when cache state is invalid

+// XXX I choose to kill an eager load L even when it is still executing.  An
+// alternative way is to re-execute L. However, this won't work well with
+// bypassing load result.  Consider L is forced to re-execute because an older
+// load L1 updates the LSQ.  When L got into the cache, it wakes up another
+// load L2 which depends on the result of L.  L will wait for L1 to first
+// execute. Suppose the store set says that L1 may dependend on a store S.
+// Then L2 will stuck at the reg read stage before S resolves its addr.
+// However, if S is waken up from reservation station after L2, then we
+// deadlock.
+
+// Fence is kept in SQ with its aq/rl bits. It is treated like an AMO , i.e.,
+// it waits for commit signal from ROB to be dequeued, and then sets the ROB
+// entry executed.
+
+// For TSO, to make our OOO execution conform to TSO, we need to *verify* each
+// load and store sequentially to mimic TSO I2E operational model. Besides the
+// sequential ordering of verification, a Ld can be verified when it has its
+// result, a St can be verified when it has addr and data computed, an
+// Lr/Sc/Amo can be verified when it has completed memory access, and a fence
+// can be verified when all older mem accesses have been dequeued from LSQ. A
+// Ld/Lr/MMIO is verified by dequeuing it from LQ, so there is no
+// verify-pointer in LQ. A Sc/Amo/Fence/MMIO is also verfied by dequeuing it
+// from SQ. The only reason for needing a verify-pointer in SQ is that a
+// verified St can still live in SQ. All stores within [deqP, verify-pointer)
+// are Sts that have been verfied, and verify-pointer points to the next store
+// to be verfied.  This pointer helps enforcing the sequential verification
+// ordering:
+// - The LQ head can be dequeued when its olderSt is invalid or older than
+// SQ verify pointer.
+// - The SQ entry at verify pointer can be verified when the LQ head's
+// olderSt is younger than or equal to this SQ entry.
+// Because of the pathological case that verify-ptr = deq ptr = enq ptr (when
+// SQ is full), we need to add a verified bit to SQ to distinguish the case of
+// everything verified from the case of nothing verified.
+
+// For WEAK, we also need verified bits and verify-ptr for SQ. These are for
+// dequeuing LQ. An LQ entry cannot be dequeud until all older SQ entries have
+// computed their addresses (pure fences can be verified as long as they are
+// valid). Note that fences do not prevent normal Ld from being dequeued, but
+// prevent normal Ld from executing. For Lr, things are trickier. Lr is issued
+// at deq time. To avoid doing a search for fences, we can just issue Lr when
+// all older SQ entries are dequeued. Same thing applies to MMIO. We add these
+// to guards of deqLd. The requirement for verification is slightly different
+// from TSO, i.e., an Sc/Amo can be verified by just computing the addr; it
+// needs not to be dequeued from SQ; and older LQ entries can still exist.

+    // never be activated in reality. TODO We can make a bypass wire to read

+    // - There is a bypassing path from validatedSt to deqSt, i.e., a store
+    // can be validated and issued to memory at the same cycle. This is
+    // probably a desirable behavior.
+    // - We put findIssue < updateAddr to prevent findIssue insert a newly
+    // updated LQ entry into issueQ; this can create problem because the new
+    // updated load may be immediately issued to execution in the same cycle
+    // later.
+    // - In TSO, only one of deqLd and verifySt can fire at one cycle, because
+    // of sequential verification requirement. In WEAK, deqLd < verifySt,
+    // because verifySt does not need to peek any info in LQ.
+    // - XXX We temporarily put deqSt < setAtCommit to avoid bypass from

+//      fabric (such as RV32/RV64 for a RISC-V CPU).

+// once for the upper 32b.
+
+// When fabric data is 64b wide, fabric addresses must be 8B-aligned
+//    - Reads always return 64b data
+//    - Write data should be 64b wide with an 8b byte-strobe indicating

+
+// ================================================================
+// This package implements a slave IP with two unrelated pieces of
+// RISC-V functionality:
+//
+// - real-time timer:
+//     Two 64-bit memory-mapped registers (rg_time and rg_timecmp).
+//     Delivers an external interrupt whenever rg_timecmp >= rg_time.
+//     The timer is cleared when rg_timecmp is written.
+//     Can be used for the RISC-V v1.10 Privilege Spec 'mtime' and
+//     'mtimecmp', and provides a memory-mapped API to access them.
+//
+//     Offset/Size        Name        Function
+//     'h_4000/8 Bytes    mtimecmp    R/W the hart0 mtimecmp  register
+//     'h_BFF8/8 Bytes    mtime       R/W the mtime     register
+//
+// - Memory-mapped location for software interrupts.
+//
+//     Offset/Size        Name        Function
+//     'h_0000/8 Bytes    msip        R/W Writing LSB=1 generates a software interrupt to hart0
+//
+// ----------------
+// This slave IP can be attached to fabrics with 32b- or 64b-wide data channels.
+//    (NOTE: this is the width of the fabric, which can be chosen
+//      independently of the native width of a CPU master on the
+//      fabric (such as RV32/RV64 for a RISC-V CPU).
+// When attached to 32b-wide fabric, 64-bit locations must be
+// read/written in two 32b transaction, once for the lower 32b and
+// once for the upper 32b.
+//
+// Some of the 'truncate()'s and 'zeroExtend()'s below are no-ops but
+// necessary to satisfy type-checking.

+
+// ================================================================
+// This package implements a slave IP, a UART model.
+//
+// This is a very basic (and very incomplete!!) model of a classic
+// 16550 UART, just enough to do basic character reads and writes.
+//
+// ----------------
+// This slave IP can be attached to fabrics with 32b- or 64b-wide data channels.
+//    (NOTE: this is the width of the fabric, which can be chosen
+//      independently of the native width of a CPU master on the
+//      fabric (such as RV32/RV64 for a RISC-V CPU).
+// When attached to 32b-wide fabric, 64-bit locations must be
+// read/written in two 32b transaction, once for the lower 32b and
+// once for the upper 32b.
+//
+// Some of the 'truncate()'s and 'zeroExtend()'s below are no-ops but
+// necessary to satisfy type-checking.
