Nisc-V

This repo contains minimal code to emulate small parts of the RISC-V ISA.

Documentation is here.

To install dependencies and build the emulator

nimble install

External requirements

sudo apt-get install libelf-dev

Installing the riscv toolchain

git clone https://github.com/riscv/riscv-gnu-toolchain
cd riscv-gnu-toolchain
./configure --prefix=/opt/riscv --with-arch=rv32i --with-abi=ilp32
make linux

To build and run the tests

nimble test

You can test on a RV32I object file using

niscv ./pathtofile.o

Next steps

I think we've got all of the RV32I instructions

1. Generate integer instruction subset

To test

Write a C program, compile it to RISC-V assembly, then compile the assembly to an object file.

Test the c program using the riscv toolchain. Then run the object file through the emulator.
