Peter McGoron 1d54b41735 fix bit width bug 2022-11-24 09:55:15 -05:00
Peter McGoron 33ec8351d8 correctly (and crudely) simulate control loop 
Issue was that the ADC cycle half wait (SCK delay) was too fast
for the input buffering (since MISO and MOSI are physical inputs
and not FPGA wires).

Peter McGoron 50ea679e02 Rewrite control_loop_math and simulate 
Replace specialized math nodes with single multiplier: each constant
must be resized to fit in the multiplier. Simplifies design at the
cost of speed.
