Facing error during OpenRAM macro generation #153

Closed vijayank88 closed 2 years ago

vijayank88 commented 2 years ago

I've cloned latest commit and installed in Ubuntu20.04 Used following command to generate sram module:

python3.8 compiler/openram.py macros/configs/sky130_sram_4kbyte_1rw_32x1024_8.py

But failed to complete the sram macro generation.

Logs:

ERROR: file magic.py: line 237: Unable to find the total error line in Magic output.
Traceback (most recent call last):

You need to install all the dependencies (Magic, Netgen, ngspice, etc.) or use the docker image which includes them. You can run the docker image with: cd macros make sky130_sram_4kbyte_1rw_32x1024
