lint_off -rule is a very new feature that requires Verilator v4.026
released in Jan 2020, and is thus not in Ubuntu 18.04. Any breakage with
newer versions should be fixed in some other backwards-compatible way.
This includes renaming Fifo.bsv to Fifos.bsv to account for a case insensitive file system which confuses this library with FIFO.bsv.
Also this includes an update of the verilator flags that are needed for modern verilator.
Finally, some verilator flag changes for building with LLVM.
Previously, the request went out into the fabric, and we were relying
on the fabric returning an error response. Some fabrics don't do this
reliably, so this removes that reliance on the fabric.
Now able to run multiple ISA tests in a single simulation run
connected to remote debugger DSharp, using either hart_reset or
ndm_reset between tests to bring the system back into reset state.
All Debug Module commands working:
- dm_reset, hart_reset, ndm_reset
- break (set breakpoint)
- step
- continue (until breakpoint of 'halt' command)
- halt
- read/write GPR, FPR, CSR, memory
- elf_load
