Quick and dirty instructions:

Checkout The Code

$ git submodule update --init --recursive

Building The Toolchain

To build RISC-V ISA simulator, frontend server, proxy kernel and newlib based GNU toolchain:

$ export RISCV=/path/to/riscv/toolchain/installation
$ cd riscv-tools
$ ./build.sh

Building The Project

To build the C simulator:

$ cd emulator
$ make

To build the VCS simulator:

$ cd vsim
$ make

in either case, you can run a set of assembly tests or simple benchmarks:

$ make run-asm-tests
$ make run-bmarks-test

To build a C simulator that is capable of VCD waveform generation:

$ cd emulator
$ make debug

And to run the assembly tests on the C simulator and generate waveforms:

$ make run-asm-tests-debug
$ make run-bmarks-test-debug

To get FPGA-synthesizable verilog (output will be in fsim/generated-src):

$ cd fsim
$ make verilog

Updating To A Newer Version Of Chisel

To grab a newer version of chisel:

$ git submodule update --init
$ cd chisel
$ git pull origin master
