@donn Is there a way to disable some warnings ? I get a lot about modules being blackboxed (no netlist/ no libs) but that's on purpose, I want them blackboxed, so having the final output filled with hundreds or irrelevant warnings is a bit annoying because it hides real infos ... Also get :

[08:54:59] WARNING  'PNR_SDC_FILE' is not defined. Using generic fallback SDC for OpenROAD PnR steps.       flow.py:629
                    'PL_TARGET_DENSITY_PCT' not explicitly set, using dynamically calculated target                    
                    density: 27.147100…

which are also irrelevant ( no logic synthesized so density is irrelevant and I have a signoff sdc but I don't run any pnr sta or is it even relevant since again this is just wiring up macros ).

Have you tried

/// sta-blackbox

?

It won't do much in this case as he doesn't have netlists listed

So I get warnings for two things : • The power gates (which have just an empty module, purly to show connectivity from logic to the control signal). For those maybe

sta-blackbox

would help. • The user modules. For which I provide a fake netlist through

EXTRA_VERILOG

. That netlist is for STA purpose only and is required to create controlled endpoints I can reference in the SDC. But there is no

.lib

and not parasistics associated. And it also doesn't reflect the real module netlist, it's just a bunch of input/output buffers connected to nothing.

Urgh… All I can do at the moment is apologize: we are looking into the warnings situation as multiple people have complained about both OpenLanes being too shouty.
