Hope the repo's back soon, I managed to clone a recent-ish version before it vanished Has anyone managed to simulate the caravel example project with the vd_io models now being available? I no longer get errors about the IO, but do get this error about fd_sc_hd.v:

/sky130A/libs.ref/sky130_fd_sc_hd/verilog/sky130_fd_sc_hd.v:35650: error: Unknown module type: sky130_fd_sc_hd__lpflow_bleeder
227 error(s) during elaboration.
*** These modules were missing:

sky130_fd_sc_hd__lpflow_bleeder_1

, is defined there, but

sky130_fd_sc_hd__lpflow_bleeder

without the

_1

is not.

_1

seems to just be a wrapper but the wrapped module seems absent

When I try to build the caravel mgmt_soc, I get this error: ../../../../rtl/caravel.v27 Include file libs.ref/sky130_fd_io/verilog/sky130_fd_io.v not found

@Philipp Gühring openlane

branch and running

build-pdk

seems to write the fd_io.v files, which seems to work on my end. I do get this other error at a later stage though

@drr, @Philipp Gühring: sky130_fd_io is the library built from the skywater-pdk repo. sky130_ef_io is a supplementary library that I wrote that mainly has some combination power pads + overlay cells, which are easier to deal with than having the overlay separate (I'm not sure the openROAD/openlane tools know how to deal with overlay cells).
