Business summary:
In Session 9 of Accellera’s “Learning PSS” video series, Tom Fitzpatrick, PSS expert and charter member of Accellera’s Portable Stimulus Working Group, explores PSS constraints and the important role they play in verification modeling. Tom explains the two main types of constraints in PSS: algebraic constraints, which relate values in random fields of actions, structs, data flow objects, and resource objects; and scheduling constraints, which control how actions are ordered based on data flow semantics or explicit scheduling directives within an activity.
