see here (Gnucap wiki). tl;dr; The issue is somewhere between model specification and simulation algorithm. The way Spice implements UIC makes no physical sense in general (cf. the currents at time 0). Particularly, (spice, ngspice) UIC was not originally intended for the purpose shown here. NB: Other simulators may do different things. Not rocket science, but at the cost of losing Spice compatibility.

I've also made the same request on GitHub in case this is the wrong place. Thanks. Since you raised it. I am not sure why the code was moved got github, probably just for the "git workflow". Today Codeberg might be a much better option, but I only recently created [1]. I will look at your patch when I find some time. [1] https://codeberg.org/qucs/gui
