Hello everyone, can anyone help me out on how I can define the width(W), length(L) and MF of a capacitor in sky130 library on xschem? thanks.

Select the capacitor and press

q

to bring up the Edit Properties popup. Then type in something like

name=C1 model=cap_mim_m3_1 W=5 L=5 MF=80 spiceprefix=X

Thanks.@Mitch Bailey,But, actually I already did that, just I don't know, For example, how can I select the W and L values for a 0.04pF or 25pF or 1pF?

thanks Mitch Bailey
