09/25/2020, 11:33 AMmy plan is to have some external address pins that hold unwanted designs in reset
Matt Venn
09/25/2020, 11:33 AMall i/o pins would be muxed

I think I should have my own supply pin, for everyone's sake, which also makes it easy to power off my circuits. Also I might not want muxed inputs and outputs either, but I might only use very few of them. Your solution could be great for digital things.

09/25/2020, 8:53 PM@Matt Venn that sounds very interesting, have you heard of the Superchip? It's a bit similar but targeted at undergraduate-level VLSI classes https://ieeexplore.ieee.org/document/4672140
