how would you define a singleton, then an entire grid of these memristor units in hdl-asm?

 

Hello there.welcome to AAC! The jury is still out on that one. Memristors (non-linear resistors with memory effect).
VHDL-AMS (and or)Verilog-AMS, offer a nonlinear network MoC, which allows you to solve nonlinear DAEs
Which you will need to implement the memriator hysterisis ("bow-tie") curve and I doubt you can do it with just ELN components.
But and that's a big but! Fraunhofer IIS/EAS have developed a framework
which integrates seamlessly into SystemC-AMS.
