  • Patent number: 8769454
    Abstract: The present disclosure teaches a system and method for register-transfer level (RTL) design checking for exploring mismatches and ambiguous language semantics that occur during the simulation and synthesis phases of the circuit design. In particular, the present disclosure utilizes identified patterns of design violations that occur as a result of these mismatches to create rule objects. The rule objects are then used to identify circuit design violations relating to mismatches between designer intent and ambiguous language. The rule objects are also categorized into different categories so as aid in the analysis of design rule violations and to identify the major impacts to the design qualities and to provide a confidence level of the overall design quality.
