@Tim Edwards Hi Tim. We are trying to do magic drc to verify our gds file. But there are some errors when reading cells (1st screenshot). And the running would be killed after a long time (2nd screenshot). The script we ran is shown in the 3rd screenshot. We found the reading cells errors also occurred when running the example SramUnit pipecleaner, but it was not killed. We’ve tried to update the magic version to the latest but it didn’t work. Do you have any suggestions for this?

The magic tech file is not designed to handle all the special layers and DRC exceptions related to SRAM. The expectation is that the SRAM macro will be abstracted before running DRC in magic.

Thanks! We will try to abstract SRAM macros first and try again.
