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.
