Method and system for analyzing a VLSI circuit design

A computer system for analyzing signals in a circuit design stored in a memory, the system comprising:

• a storage medium;
• and
• a processor for executing a software program stored on the storage medium for analyzing a circuit design, the software program comprising a set of instructions for:
• performing an analysis of the circuit design using an electronic computer-aided design (E-CAD) tool;
• identifying signals having violations of specifications for the circuit design;
• storing names of signals having violations to a violations file;
• reconfiguring the E-CAD tool after performing the analysis, based on the violations;
• and
• rerunning the analysis only on the signals having violations, after the reconfiguring.

A computer-readable medium having computer-executable instructions for performing a method for analyzing a computer representation of a circuit design having a plurality of layout segments with signals transmitted on said segments, the method comprising:

• performing a first analysis of a circuit design using an electronic computer-aided design (E-CAD) tool;
• identifying segments in the design that violate specifications;
• identifying signals on the segments having violations;
• determining whether each violation is an actual violation;
• if the violatiion is an actual violation, fixing the violation;
• if the violation is not an actual violation, reconfiguring the specifications;
• and
• performing a second analysis of the circuit design based upon the signals having violations, wherein the step of performing the second analysis comprises rerunning the first analysis only on the signals having violations, after the reconfiguring.
