| +## Parallel runs |
| +When running against the `verilator` target parallel make jobs are used (via |
| +passing `-j4` to make internally). Parallel runs can be disabled by passing |
| +`PARALLEL=0` to the `make` command or the `-j` used can be altered with the |
| +`JOBS` argument. |
| + |
| +Disable parallel runs: |
| +```console |
| +$ make RISCV_ISA=rv32i PARALLEL=0 |
| +``` |
| + |
| +Use a different `-j` parameter: |
| +```console |
| +$ make RISCV_ISA=rv32i JOBS=-j8 |
| +``` |

| ## Removed/Broken Tests |
| A small number of tests are not run for OpenTitan riscv_compliance as they fail |
| due to flaws in the compliance test suite rather than Ibex/OpenTitan itself (see |
