Hello everyone, I am looking for help to run a gate-level simulation using OpenLane with sky130_fd_sc_hd and QuestaSim. I am having issues with the .sdf file. Basically, I have loaded a design and ran the flow in OpenLane. Now, I am trying to load the following files in QuestaSim:
primitives.v
sky130_fd_sc_hd.v
my_module.v
my_module.sdf
I got these messages when QuestaSim loads the sdf file:
# Loading instances from my_module.sdf

# ** Error (suppressible): (vsim-SDF-12088) my_module.sdf(34): Failed to find matching specify module path for IOPATH.

How can I correctly load the sdf file? Thanks.
