Error in using sram macro in openlane2

[FriedrichWu]

Description

Hello,

I encountered some errors in trying to use sram macros in openlane2. The openlane2(magic) complains that some cells are placed at itself, and unknown layer/datatype in boundary. I also try just to use only the bank extracted from the sram macro, but failed with similar error.

According to the developer, these are necessary layers in macro.

There is also one similar error -> https://github.com/The-OpenROAD-Project/OpenLane/issues/1040

Expected Behavior

do not fail at this stage and continue running

Environment report

null

Reproduction material

Openram1.2.48, Openlane 2.0.0rc2(but 2.04 has same problem) macro_test.zip

Relevant log output
