Part 1: Schematic Capture with Xschem While it’s possible to just draw transistors directly - for example in SiliWiz, this doesn’t scale well and gets confusing fast. We want to draw a circuit diagram first, with levels of hierarchy for more complex designs. These can then be simulated and checked that specifications are met before moving onto layout. Lab 1.1: Try the Xschem demos Build Xschem familiarity. Experiment with some of the demos that come with the PDK. Lab 1.2: Draw your own ci...
