At this level? You can use your favourite HDL and a FPGA, and then look into things like TinyTapeout and such. It's not as inaccessible as it seems!

HDL is fun and all, but actually choosing the physical layout and sizing of transistors seems like a much more fun puzzle.

It does take a time investment, but it’s absolutely possible today. https://tinytapeout.com/specs/analog/

If you’re willing to do something that’s not manufacturable, but way easier to understand, then you might try this: https://tinytapeout.com/siliwiz/
