Error in using sram macro(tiny) in openlane2

[FriedrichWu]

Describe the bug
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.

I'm not sure if it's about the gds file, but it looks fine when opening with klayout

There is also one similar error -> The-OpenROAD-Project/OpenLane#1040

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

To Reproduce

macro_test.zip

Expected behavior
No error in reading gds

The layer errors are complaining about necessary layers in the macro. These are for OPC etc and cannot be removed.

Thanks for the quick response.

I see. Then it's probably the problem of the openlane. Is there maybe any workaround to make the tool to recognize those necessary layers?

It's shown as an error, but it is really a warning.
