Method and System for Performing Heuristic Constraint Simplification
First Claim
1. A computer verification system, said system comprising:
- means for selecting a first computer-design constraint for simplification;
means for applying structural reparameterization to simplify said first computer-design constraint;
means for, in response to determining that said first computer-design constraint is not eliminated, setting said first computer-design constraint equal to a dead-end state of said first computer-design constraint;
means for creating a structural preimage of said first computer-design constraint; and
means for, in response to determining that a combination of a target and said dead-end state of said first computer-design constraint is equal to a combination of said target and said structural preimage of said first computer-design constraint, setting said first computer-design constraint equal to said structural preimage.

Abstract
A method for performing verification is disclosed. The method includes selecting a first computer-design constraint for simplification and applying structural reparamaterization to simplify the first computer-design constraint. In response to determining that the first computer-design constraint is not eliminated, the first computer-design constraint is set equal to a dead-end state of the constraint. A structural preimage of the first computer-design constraint is created, in response to determining that a combination of a target and the dead-end state of the first computer-design constraint is equal to a combination of the target and the structural preimage of the first computer-design constraint, the first computer-design constraint is set equal to the structural preimage.
