Issue created by <https://github.com/JiaDYuan|JiaDYuan>
*Description*

I was using OpenLane to try to pass the VLSI flow of LDPC project. This LDPC is pure logic without memory needing to be dropped in sram. But I failed in the stage of resize. Here are the error messages:

[ERROR]: during executing openroad script /openlane/scripts/openroad/resizer.tcl

[ERROR]: Flow failed.

*Expected Behavior*

I want to pass the VLSI flow of the LDPC project in OpenLane.
