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
- 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 add remote 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
