<@U01E2KKE4SH> :  The lpflow_bleeder was an error I noticed a while ago and made a patch for yesterday, so it the library was updated very recently.  A submodule udpate should grab it.

Thanks <@U016EM8L91B>, made progress by updating PDK to master and also cloning the new hvl submodule

This is now as far as I get as there is no DFFRAM.v in the project, although there is a <http://DFFRAM.gl|DFFRAM.gl>.v which I'll try to make it use:

```../../../../rtl/mem_wb.v:83: error: Unknown module type: DFFRAM
511 error(s) during elaboration.
*** These modules were missing:
        DFFRAM referenced 1 times.
***
make: *** [io_ports.vvp] Error 255```


After doing that and patching the Makefile in a few spots, io_ports.tb seems to pass :+1:

I would be happy if somebody could explain (or get rid of) the "input port clock is coerced to inout" warning.  It does not seem to affect behavior in any way, but it bothers me and I can't figure out what causes it.  As far as I can see the port is no different than other ports that are being used as digital inputs in the same way.
