I have nmigen code mixed with other RTL language code so am using external simulator. With this option I can now turn off the memory preparation for pysim for all generated blocks.

from nmigen import *

Memory.simulate = False

I'm rewriting the simulator right now so that it would not need the (expensive) memory lowering. So I'll keep this open, with the understanding that Memory.simulate will go away completely.
