Randomization with Constraints: Pitfalls

Pitfalls and red flags

• Using randc on very large domains and expecting practical no-repeat behavior.

• Adding inline with constraints that contradict base class legality constraints.

• Ignoring randomize() return value and using uninitialized or stale data.

• Writing implications that accidentally over-constrain due to broad antecedents.

• Treating solver failure as simulator bug before checking constraint math.
