A question about where new cells get saved - when I create a pcell in magic, or they get created when I import a spice netlist, is there a way to set the path where they are created / saved? I have been manually moving them to a sub directory and then editing the mag files by hand to give the directory

There is no convenient way to do this automatically; you would need to do

cellname filepath <cell> <path>

for each generated cell. It would not be too difficult to add a method to assign a path for new generated cells. The reason I never did that was that I was considering a different method where all generated cells would end up in the same file, but I never implemented it. Probably specifying a path is a better way to do it, anyway.

ok, thanks
