++title: "OpenTitan RISC-V Compliance Testing" ++--- ++ ++# Overview ++The RISC-V compliance test can be run on either FPGA or Verilator. ++To run on Verilator, set the variables below ++ ++```console ++$ export RISCV_TARGET=opentitan ++$ export RISCV_DEVICE=rv32imc ++$ export TARGET=verilator ++``` ++ ++To run on FPGA, set the variables below. ++The `FPGA_UART` variable must be set to wherever a valid device is connected. ++ ++```console ++$ export RISCV_TARGET=opentitan ++$ export RISCV_DEVICE=rv32imc ++$ export TARGET=fpga ++$ export FPGA_UART=/dev/tty* ++``` ++ ++By default, the test assumes there exists a valid Verilator build at `${REPO_TOP}/build/lowrisc_systems_top_earlgrey_verilator_0.1/sim-verilator/Vtop_earlgrey_verilator`. ++If your Verilator build is at a different location, please set that as well when running with Verilator. ++For instructions on how to create a Verilator build, please refer to the [Verilator guide]({{< relref "doc/ug/getting_started_verilator" >}}). ++ ++```console ++$ export TARGET_SIM=${PATH_TO_VERILATOR_BUILD} ++``` ++ ++When running against FPGA, the test assumes the FPGA is already programmed and ready to go. ++To find out how to properly build and flash FPGA, please refer to the [FPGA manual]({{< relref "doc/rm/ref_manual_fpga" >}}) ++ ++ ++Now, run the tests. ++The following output will be seen (software build steps are truncated). ++The example below uses Verilator as an example, but the FPGA output is nearly identical. ++ ++```console ++$ cd $REPO_TOP ++$ make -C
