SETUPTIME_LO = SETUPTIME_HI = If either of the time values is 0, then no check is done for that case. HOLDTIME is used in the same way as SETUPTIME and also has the alternate _LH and _HL formats and 0 value condition. RELEASETIME causes the simulator to perform a special-purpose setup check. Release time (also referred to as recovery time in some data sheets) refers to the minimum time that a signal can go inactive before the active clock edge. Again, the _LH and _HL forms are available. The difference between RELEASETIME and SETUPTIME checking is that simultaneous CLOCK/DATA transitions are never allowed (this assumes a nonzero hold time). RELEASETIME is usually not used in conjunction with SETUPTIME or HOLDTIME. Width WIDTH does the minimum pulse-width checking. MIN_HI/MIN_LO is the minimum time that the node can remain HI/LOW. The value must be a nonnegative constant, or expression. A value of 0 means that any pulse width is allowed. At least one of MIN_HI or MIN_LO must be used within a WIDTH section. Freq FREQ checks the frequency. MINFREQ/MAXFREQ is the minimum/ maximum frequency that is allowed on the node in question. The value must be a nonnegative floating point constant or expression measured in hertz. At least one of MINFREQ or MAXFREQ must be used within a FREQ section. AFFECTS clauses (not used in this example) can be included in constraints to describe how the simulator should associate the failure of a constraint check with the outputs (paths through the device) of the PINDLY. This information does not affect the logic state of the outputs but provides causality detail used by the error tracking mechanism in PSpice A/D waveform analysis.
