# 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
|
|
```
