IO Timing Details
All analog IOs are updated/sampled at the beginning of each simulation time step
(t1), which is software defined. To improve the PWM sampling
resolution, digital inputs actually are sampled at a higher rate (t2),
independent of the simulation time step value. Similarly, digital outputs are
updated at a higher t2 rate. For overall expected loop-back latency,
please consult Loopback Latency.
