Requirements

• SystemVerilog simulator
• CMake
• 32-bit GNU RISC-V toolchain

If your package manager does not provide the RISC-V GNU toolchain you can compile it from their main repository or for Windows you can download the xPack pre-compiled binaries.

Build

To build the firmware that will be loaded in the instruction memory execute CMake in the fw directory specifying the RISC-V toolchain and build the recipe based in your selected generator (make in the following example).

cmake -DCMAKE_TOOLCHAIN_FILE=./cmake/toolchain.cmake -Bbuild
make -Cbuild
