From a Wokwi schematic to a GDS file

Build and test a two-input AND gate in Wokwi, then use GitHub Actions to turn it into a SKY130 chip layout. At the end, you will have a GDSII (.gds) file, a 2D preview, and an interactive 3D view of your layout.

You can complete this workshop in your browser. The switches and LED help you test the circuit in Wokwi; the logic between the input and output buffers becomes the chip design.
