Congruent weak conformance
R.W. Brower, Kenneth S. Stevens · 2002
Congruent weak conformance is a property between formal models capturing the desired relationship between a specification and its implementation by allowing unused and redundant circuitry and tolerating unspecified behavior in the unreachable state space. By providing greater flexibility in design than previous properties, it becomes a useful tool to validate transformational systems, such as logic synthesis and hardware description language translation systems.
