30_openram_back_end_test using calibre and freepdk45

[bvhoof]

commit: b3e249c722d33

although overriding the drc/lvs/pex tools to calibre, it still errors on: ERROR: file globals.py: line 253: magic not found If I insert print statements before, it prints 'calibre' and the correct path.

Any ideas?

Best regards, Bob.

I'm not able to replicate this -- it works fine on my computer. How are you running the test?

$ ./30_openram_back_end_test.py -t freepdk45

I ran this exactly the same as you. I run in an anaconda environment with all correct stuff installed. I installed magic and netgen (which I don't really need) Now, it goes a bit further into the code, but it still crashes on the same issue.

For some reason, it thinks that magic is the DRC tool: If I print OPTS.drc_exe in the verify/init.py, it prints the correct tool: calibre If i print the inspection in the base/hierarchy_design.py right under the import verify statement of the DRC_LVS() definition:

import verify
import inspect
print(inspect.getmodule(verify.run_drc))

It does not print that, it crashes beforehand, altough it says in the stack trace that it got further than that statement.

Can you point me in a direction how this might happen?

Thanks, Bob
