@User: We need a specific place to go that has a directory listing all of the IP available---sort of like opencores.org but covering everything analog, digital, and mixed-signal. Plus, not attempting to be its own repository but just a place to organize the IP and link to github.

I could probably throw together a quick database app for people to add their design metadata and links. Could run it on app engine. Don't have time to put together anything too fancy but other one can always add to it

maybe just a simple google drive spreadsheet would do the trick?

@Anish a good starting point. I think that longer term, something with proper permissions/ownership and such is a good idea. Here's a google sheet for people to get started, along with an example. Feel free to add additional columns if needed.

Makes sense - it would def be nice to have something like opencores but for mixed-signal stuff

I think those FPGA estimates are pulled from real data after generating bitstreams. Something like that could easily be done as the sky130/openpdk makefiles evolve (add your own cell, run make to generate the various files needed, calculate and print cell sizes)
