07/06/2023, 1:49 AMhello, can someone tell me what is https://github.com/google/skywater-pdk-libs-sky130_fd_pr ?
I can't find any example of implementation with this library and its rf_nfet components (rf_ mean reference frequency ? radio frequency ?)

I ask if this specific subpart has a proven use case.

07/06/2023, 10:56 AMok so that's what I thought, nothing is provided at the moment to use it in the flow.
Next question...
how to integrate this kind of thing into the flow...
I need to search in the documentation, but if you have an advice to learn how to do it, i take it with pleasure aha
