Sir, Is it possible to get a GDS file by using Xschem for schematic capture and magic for layout i.e., through full custom design flow

@Saumeek Upadhyay you can import a spice netlist (created with xschem) into magic, but it will only create the devices. You’ll need to manually position and wire the layout.

Thank you sir!

(a) align, (b) bag, (c) RALF. All open source. All three are kind of "automatic" spice-to-gds converter. Im not involved, but to my knowlage the last one comes with sky130 examples. Ask Harald Pretl for details. (looks like RALF is part of a prerelease of his IIC-OSIC-TOOLS collection)

Thank you sir!
