Hello, I am trying to use gf180 in order to run through the digital flow,  however I am running into this error that I am unsure how to find information to solve. 

120. Executing JSON backend.

It appears that I can find them in: runs/RUN_2025-11-17_22-01-17/07-checker-yosysunmappedcells but the only information I get from it is I have 2 unmapped instances, nothing about what it is. Could someone point me in the right area to fix this?

Hi, I assume you made changes to the template? If so, which changes did you make?

If those two unmapped cells are the SRAM macros: To remove the SRAM macros, you need to remove the instances from the RTL, the `config.yaml` and the `pdn_cfg.tcl`.
