# DBT-RISE-TGFS
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 .
# DBT-RISE-RISCV
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~~.
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/RISCV-VP which models SiFives FE310 controlling a brushless DC (BLDC) motor.
This library provide the infrastructure to build RISC-V ISS. Currently part of the library are the following implementations adhering to version 2.2 of the 'The RISC-V Instruction Set Manual Volume I: User-Level ISA':
* RV32I (TGF-B)
* RV32MIC (TGF-C)
* RV32IMAC
* RV32GC
* RC64I
* RV64GC
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).

For further information please have a look at [https://git.minres.com/VP/RISCV-VP](https://git.minres.com/VP/RISCV-VP).
Last but not least an SystemC wrapper is provided which allows easy integration into SystemC based virtual platforms.
Since DBT-RISE uses a generative approach other needed combinations or custom extension can be generated. For further information please contact [info@minres.com](mailto:info@minres.com).

# 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).
