I am trying to set up a make system that has magic generate some layouts from commands in a tcl file but am having some issues. If I launch magic and then run the file with

source pmos_waffle_8_gen.tcl

it runs fine. But if I try to launch magic with

magic -T sky130A pmos_waffle_8_gen.tcl

I get some errors. Can anyone advise me on how to get this working?

References to "titlebar.caption" refer to the window, and it may have something to do with the script being read before the window is generated. You can try several different things. . . One would be to run

magic -dnull -noconsole

to make sure it doesn't expect a window. I assume you are running this in "batch mode", as otherwise you could just do what you did originally, typing the

source

command at the command prompt. There are other possibilities that I can tell you about if the solution above doesn't match your use case.

Sweet, thanks!

magic -T sky130A -dnull pmos_waffle_8_gen.tcl

worked. My generation is only parameterized in terms of the grid size (not pitch) but I am hoping to split out the waffle fet generation from my project and nicely package it up. Two of the layouts are even tested via tapeout, so it should be pretty useful
