Hi Does anyone know about this error? [ERROR MPL-0004] No macros found Error: basic_mp.tcl, 30 MPL-0004

I am guessing this is a custom flow. The macro placer is being called but there are no macros in the design (i.e. LEF

CLASS BLOCK

). If there are no macros, macro place should be skipped.

Yes I have one file .LEF

See e.g. https://github.com/The-OpenROAD-project/OpenROAD-flow-scripts/blob/master/flow/scripts/macro_place.tcl
