006_vec_signal_state : Check output vs expected signal states
Requires: SmartSpice & Smartview
Minimum Versions: SMARTSPICE 3.16.12.R
The .vec statement keyword "check_window" allows a user to perform steady and non-steady checks of the actual signal states against the expected states. In this example we use non-steady state checks.
