Examples do not build / sim / work (?)

[filmil]

I'm expecting this to be a case of PEBKAC, but still.

I tried following the instructions at https://github.com/fusesoc/blinky?tab=readme-ov-file#how-to-use

Here are the results. What am I doing wrong? I also tried to download the blinky source from here, and run in that dir. No impact.

This helped a bit:

(pyenv) ┬─[f@filmar:~/tmp]─[04:40:40 AM]                                                                                                     
╰─>$ fusesoc library add blinky https://github.com/fusesoc/blinky
...

However:

╰─>$ fusesoc --config fusesoc.conf run --target=sim fusesoc:utils:blinky

What to do?

Aha! I see now that the README instructions aren't complete. I have updated them now. The simulation target depends on the vlog_tb_utils core. That one is found in another library, which needs to be added to the workspace. Running fusesoc library add fusesoc-cores https://github.com/fusesoc/fusesoc-cores should do the trick.
