 1. Set `$RISCV` to wherever you want the tools to be installed to. i.e. `export RISCV=~/riscv-tools`
 2. Run [`./cva6/ci/setup.sh`](https://github.com/openhwgroup/cva6/blob/master/ci/setup.sh). (If you get an error, you may need to rerun parts of the script manually).
-3. In ["./setup.sh"](https://github.com/openhwgroup/cva6/blob/master/ci/setup.sh), change the `$RISCV` initialization to whatever you chose for step 1.
+3. Install the [OSS CAD Suite](https://github.com/YosysHQ/oss-cad-suite-build). You can do this by un-taring the latest release to a `"~/Utils/oss-cad-suite"` directory.
+4. Add the following to your `"~/.bashrc"`, and replace the values of the 3 environment variables:

 ### linux.engr.ucsb.edu Tool Setup
 
-1. Set `$RISCV` to `/ece/riscv` using `export RISCV=/ece/riscv`.

 4. To view the waves, run `gtkwave dump.vcd`. (This should probably be done in another terminal to not interfere with running more simulations.)
