IO Timing

Sample rates and timing details for HIL 4/6 Series devices.

Sample Rates

Table 1. HIL402, HIL602+, and HIL604 IO sample/update rates
IO class	Sample/Update rate	Comment
Digital input	160 MSPS	All digital inputs are sampled simultaneously.
Digital output	Up to 160 MSPS	All digital outputs are updated simultaneously.
Analog input	1/t₁	All analog inputs are sampled simultaneously. Minimum sample time is 1μs
Analog output	1/t₁	All analog outputs are updated simultaneously.

Table 2. HIL404 and HIL606 IO sample/update rates
IO class	Sample/Update rate	Comment
Digital input	280 MSPS	All digital inputs are sampled simultaneously.
Digital output	Up to 280 MSPS	All digital outputs are updated simultaneously.
Analog input	1/t₁	All analog inputs are sampled simultaneously. Minimum sample time is 1μs
Analog output	All analog outputs are updated simultaneously.

IO Timing Details

All analog IOs are updated/sampled at the beginning of each simulation time step (t₁), which is software defined. The only exception is for HIL606 devices running at a 200 ns simulation step; in this case, all analog outputs are updated on every other time step (400 ns). 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 an exact t₂ value, check the table above corresponding to your HIL device(s). For overall expected loop-back latency, please consult Loop-back Latency.
