Block-level DV for all of the IP blocks vendored from OpenTitan can also be run using DVsim.
Many blocks default to running using VCS, but they can be forced to use Xcelium using the `-t xcelium` option.
At the time of writing, spi_host was having issues running properly on Xcelium but all other blocks pass their smoke regressions.

The smoke test for each of the blocks can be run using Xcelium with these commands:
The full regression (called nightly) for each of the blocks can be run using Xcelium with these commands:

```sh
# -- Build and run block-level tests using Xcelium --

# Run aon_timer smoke regression

Like the top-level DVsim tests, artefacts end up under *scratch/* and additional output can be generated using the `-w shm` and `-v h` options.
