Abstract

See full text

Optimizing timing in a VLSI circuit by generating a set of buffer solutions and determining a most critical delay and a sum of critical delays for each solution in the set of solutions. Quantifying a relationship between the most critical delay and the sum of critical delays for each solution. Comparing each solution's quantified relationship to the quantified relationship of each other solution in the set of solutions. Identifying, based on the comparing of each solution's relationship to the relationship of each other solution in the set of solutions, at least one solution in the set of solutions to have a worse relationship between the most critical delay and the sum of critical delays than the other solutions in the set of solutions. Pruning the at least one solution from the set of solutions.
