Ariane RISC-V CPU

For detailed documentation refer to the online documentation (Login: zarubaf Password: zaruba).

Getting Started

Go and get the RISC-V tools.

Checkout the repository and initialize all submodules

git checkout git@iis-git.ee.ethz.ch:floce/ariane.git
git submodule update --init --recursive

Build Ariane by using the Makefile:

make build

Start the simulation using Modelsim:

make sim

To specify the test to run use (e.g.: you want to run rv64ui-p-sraw inside the riscv-tests isa folder:

make sim riscv-test=rv64ui-p-sraw

If you call simc instead of sim it will run without the GUI.

Or start any of the unit tests by:

make dcache_arbiter
