Is there an easy way to turn text into polygons so masks can be documented? I have a 4-mask university-based nmos transistor process, and it is very helpful to have things labeled in the physical mask. I am sure one could just draw the letters as cells and call them with a TCL script, but if this process already existed, that would save me time.

In sky130, there is a library

sky130_ml_xx_hd

containing layout in magic format with hex values of the ASCII for each character (e.g.,

font_6C.mag

) in the

mag/

directory. In the

scripts/

directory there is a python script called

text2mag.py

that will compose a layout file from a text string.
