Abstract: A computer-implemented method, system and computer program product for recommending design changes in designing a digital integrated circuit. An analysis of the digital integrated circuit being designed is performed, where the result of such an analysis involves violations being identified and stored. A stored violation, such as a cross-domain, cross-hierarchy and multi-cycle violation, may then be analyzed to identify a root cause of the violation using a rule. Such a rule may be used for triaging various failures in the cross-domain, cross-hierarchy and/or multi-cycle violation of the digital integrated circuit. A design change in the design of the digital integrated circuit may then be recommended based on the identified root cause of the violation. In this manner, the root cause of failures are effectively identified in the design of digital integrated circuits using an offline analysis of cross-domain, cross-hierarchy and/or multi-cycle violations using a rules-based approach.

Abstract: A novel logic design method for avoiding wiring congestion. According to the novel logic design method, an original gate having multiple inputs coming from different directions and having multiple outputs coming to different directions can be transformed to a logic block that has an input stage and an output stage. The gates of the input stage receive signals from the multiple inputs of the original gate. The gates of the output stage send signals to the multiple outputs of the original gate. Each gate of the input stage is placed in a vicinity of its inputs. Each gate of the output stage is placed in a vicinity of its outputs. The gates of the input and output stages are functionally equivalent to the original gate.
