So I am looking to run a spice simulatio, Since I do not have much spice experience I would like some help finding some example/instructions, preferably something sky130 and openlane specific

For an analogue flow intro, these are some good places to start that will describe the schematic setup (maybe not needed?) but also simulation, waveform viewing etc. https://github.com/StefanSchippers/xschem_sky130/blob/main/sky130_fd_pr/README.md https://github.com/StefanSchippers/xschem_sky130/blob/main/sky130_stdcells/README.md https://github.com/bluecmd/learn-sky130/blob/main/schematic/xschem/getting-started.md

thanks, I will have a look

There's a PLL design set to be included in the management harness on all chips

I didn't have a look at the harness yet, but I remember a PLL would be a part of it being mentioned in the talk.
