DBT-RISE-RiscV

Am instruction set simulator based on DBT-RISE implementing the Risc-V ISA

DBT-RISE-RiscV README

This is work in progress, so use at your own risk. Goal is to implement an open-source ISS which can easily embedded e.g. into SystemC Virtual Prototypes. It used code generation to allow easy extension and adaptation of the used instruction. The Risc-V ISS reaches about 20MIPS at an Intel Core i7-2600K.

The implementation is based on LLVM 4.0. Eclipse CDT 4.7 (Oxygen) is recommended as IDE.

DBT-RISE-RiscV uses libGIS (https://github.com/vsergeev/libGIS) as well as ELFIO (http://elfio.sourceforge.net/), both under MIT license

What's missing

  • RV64I is only preliminary verified
  • F & D standard extensions to be implemented

Planned features

  • add platform peripherals to resemble E300 platform
    • PLIC
    • gpio
    • ...
  • and more

Quick start

    pip install conan
  • download and install SystemC from http://accellera.org/downloads/standards/systemc (this is going to be replaced with a conan.io integration)
    • optionally download and install SystemC Verification Library (SCV) from Accelera into the same location
  • setup conan to use the minres repo
    conan add remote minres https://dl.bintray.com/minres/conan-repo
  • checkout source from git
  • start an out-of-source build like so (e.g. when using bash)
    cd DBT-RISE-RiscV
    mkdir build
    cd build
    cmake ..
    cmake --build .
  • if the SystemC installation is not found by cmake you can optionally specify the location by either setting the following environment variables pointing to the installation
    • SYSTEMC_HOME
    • SYSTEMC_PREFIX
  • if you encounter issues when linking wrt. c++11 symbols you might have run into GCC ABI incompatibility introduced from GCC 5.0 onwards. You can fix this by adding '-s compiler.libcxx=libstdc++11' to the conan call or changing compiler.libcxx to
compiler.libcxx=libstdc++11
