### Quick Start
Setup Vortex environment:
```
$ export RISCV_TOOLCHAIN_PATH=/opt/riscv-gnu-toolchain
$ export PATH=:/opt/verilator/bin:$PATH
$ export VERILATOR_ROOT=/opt/verilator
```
Test Vortex with different drivers and configurations:
- Run basic driver test with rtlsim driver and Vortex config of 2 clusters, 2 cores, 2 warps, 4 threads
$ ./ci/blackbox.sh --clusters=2 --cores=2 --warps=2 --threads=4 --driver=rtlsim --app=basic
- Run demo driver test with vlsim driver and Vortex config of 1 clusters, 4 cores, 4 warps, 2 threads
$ ./ci/blackbox.sh --clusters=1 --cores=4 --warps=4 --threads=2 --driver=vlsim --app=demo
- Run dogfood driver test with simx driver and Vortex config of 4 cluster, 4 cores, 8 warps, 6 threads
$ ./ci/blackbox.sh --clusters=4 --cores=4 --warps=8 --threads=6 --driver=simx --app=dogfood
