xschem. A schematic editor for VLSI/Asic/Analog custom designs, netlist backends for VHDL, Spice and Verilog. The tool is focused on hierarchy and parametric designs, to maximize circuit reuse.

xschem_sky130. XSCHEM symbol libraries for the Google-Skywater 130nm process design kit.

xschem-gaw. gaw3-20200922 fork with patches to improve remote commands sent from xschem to display waveforms

sky130_schematics. Verified visual schematics for all SKY130 Cells

3bit_sar_adc. 3 bit sar adc with real mixed signal simulation using xschem, ngspice, and verilator. Transistors used are from the open source sky130 PDK. Features a 3 bit DAC, fed into a sample and hold circuit, then fed into a comparator. The comparator creates a digital output value fed into the verilog block

IHP-Open-PDK. 130nm BiCMOS Open Source PDK, dedicated for Analog, Mixed Signal and RF Design
