I can modify the diode symbol to require W and L parameters and output AREA and PJ in netlist, however this change will probably break existing designs where diodes are...

OK will do asap

@RTimothyEdwards For diodes i need to set AREA=1e12 to get an I-V current that is reasonable for a 1um x 1um diode (some uA at 700mV Vbe) Should the corresponding...

I think it's a scaling issue in the model. simulating a diode with AREA=1e12 and PJ=4e6 yields an I-V forward characteristic that makes sense for a 1um x 1um silicon...

@RTimothyEdwards I have done some tests. With ngspice i can specify W=.. L=... instead of AREA=... PJ=... Putting W=1e6 L=1e6 i get same results as shown above for AREA=1e12 PJ=4e6....

Upstream [xschem_sky130](https://github.com/StefanSchippers/xschem_sky130) symbols for diodes will output Area and Pj. @RTimothyEdwards i also noticed that although a dc simulation of the diodes will show a "reasonable" I/V characteristic if using...

Exact same problem on a Debian machine with sdl_ttf 2.20.1. I have seen the above issue about surface change in SDL_ttf, however wondering what I should do to get text...

The `vsource.sym` is not a sky130 specific device, it is a generic SPICE voltage source. It is packaged with xschem. How did you install xschem? the recommended way to install...

Looking at scikit-rf it uses a python description of the RF circuit, so to use a library of RF elements a different "netlist" backend must be created. A Spice netlist...

So what you want to do is to have some Opto/RF symbols in xschem, create a circuit (by placing and connecting these elements) and get the circuit description that SAX...
