Well, transmission gates are already on the list. Or being more earnest
- they are the point where my Standard Cell Library stuck. Most
effective (in meaning of size and transistor count) cells with storage (Latches) and multiplexer are based on transmission gates.
I really like to measure both transistors first, as components, before I compose transfer gates out of them. So they don't get it to the PearlRiver.
For static measurements, this is the way to go. For high speed and precision measurements, where parasitic capacitances play a role, dedicated transmission gate test structures make sense - as a second step.
But yes, transfer gates are feasible, on the wish list and you'll get them as soon as the PMOS and NMOS are characterized with PearlRiver :-)
Isolated bulk and high voltage switches for charge pumps etc. are also insteresting ... as later step.
And regarding your NxN crossbar - for a quite nice RISC-V multiplier I already planed to hand-crafting a Barrel Shifter (https://en.wikipedia.org/wiki/Barrel_shifter) which is a structure close to your crossbar.
As essentially analog guy, I tend to want to focus on basic building blocks first.
