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

• F & D standard extensions for 32bit to be implemented
• MACF &D standard extensions for 64bit to be implemented and verified

Planned features

• add platform peripherals beyond programmers view to resemble E300 platform
  • QSPI
  • PWM
  • ...
• and more

Quick start

• you need to have a decent compiler, make, python, and cmake installed
• install LLVM 4.0 according to http://apt.llvm.org/ (if it is not already provided by your distribution)
• install conan.io (see also http://docs.conan.io/en/latest/installation.html):

    pip install conan

• setup conan to use the minres repo:

    conan remote add minres https://api.bintray.com/conan/minres/conan-repo

• checkout source from git
• start an out-of-source build:

    cd DBT-RISE-RiscV
    mkdir build
    cd build
    cmake ..
    cmake --build .

• 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
