Core of an instruction set simulator based on DBT-RISE implementing Minres The Good Folks Series cores. The project is hosted at https://git.minres.com/DBT-RISE/DBT-RISE-TGFS . Core of an instruction set simulator based on DBT-RISE implementing the RISC-V ISA. The project is hosted at https://git.minres.com/DBT-RISE/DBT-RISE-RISCV .
This repo contains only the code of the RISC-V ISS and can only be used with the DBT_RISE. A complete VP using this ISS can be found at https://git.minres.com/VP/Ecosystem-VP ~~which models SiFives FE310 controlling a brushless DC (BLDC) motor~~.

All pass the respective compliance tests. Along with those ISA implementations there is a wrapper (riscv_hart_m_p.h) implementing the Machine privileged mode as of privileged spec 1.10. The main.cpp in src allows to build a stand-alone ISS when integrated into a top-level project. For further information please have a look at [https://git.minres.com/VP/RISCV-VP](https://git.minres.com/VP/RISCV-VP). All pass the respective compliance tests.

Last but not least an SystemC wrapper is provided which allows easy integration into SystemC based virtual platforms. Last but not least an SystemC wrapper is provided which allows easy integration into SystemC based virtual platforms.

# pctrace
Trace functionality to allow visualizing coverage in lcov and cachegrind tools. Use environment variables NOCOMPRES and REGDUMP to toggle functionality.
- NOCOMPRES: any value turns off the LZ4 compression
- REGDUMP: any value switches to tracing the registers instead. Also turns off compression.
Known Bugs:
- currently does not work correctly with jit backends, the plugin cant tell if instructions are compressed. Additionaly the cost of instrs that raise a trap is not known. It takes the cost of the instrid -1 (0 at the moment).
