switch (e.g., magic -d XR -rcfile /path/to/sky130A.magicrc
), which runs (among other things important to the PDK setup) a grid scaling that scales from lambda (an initial grid scaling chosen somewhat arbitrarily) to the minimum manufacturing grid. If you're not using -rcfile
(hint: you should), you can scale the grid down with the scalegrid
command.Nelson Rodriguez

, I still have to run snap grid
because without it I can't work with the smallest dimensions.
Now, let's say I type the above commands and also paint some lines using source
command (because they are described in a tcl file) and save all of that. Once I want to open it again, nothing is saved, I have to type one more time the snap grid
and source the tcl file with the lines again.
Is there a solution to keep the effect of those commands in my previous work session?Tim Edwards

command just draws grid lines. If you want to draw on the fine scale, just use snap internal
(what you did is fine, too, just a bit more roundabout).
If you are drawing geometry from the command line (or a script file), the grid
and snap
are irrelevant as long as you specify units (e.g., box 10um 10um 20um 20um; paint m1
)
"save all of that" followed by "nothing is saved" is contradictory. Can you provide an example of something you scripted? (A common misunderstanding is using the save
command instead of the writeall
command, which could be the issue here.)
