A method and system for performing consistency checking of one or more design representations having different design types. A translator for each design type obtains information from each design needed to evaluate rules that are design type-neutral. The described examples also allow a user to add rules using predefined rule terms. In addition, certain examples allow the user to add terms to the rule set and to make new rules with the added terms. Each new term added to a rule set has a corresponding abstraction function in a translator for each design type. Thus, the abstraction functions are not design type-neutral.

Multi-format consistency checking tool

A method and system for formally verifying designs having elements from more than a single design domain is described. An example system allows formal verification of a design containing mixed analog and digital subparts. The system may use different proof engines to solve an appropriate sub-partition of the entire design, and may provide a framework for translating between the different domains to create a unified result. For example, a digital proof engine may be used for a digital only subpart, while an analog proof engine may be used for an analog only subpart. The system may use the partitioning results to determine translators between the various domains, and an order in which the proof engines are applied.
