Abstract
A system for creating protected functional descriptions of integrated circuits provides encrypted gate delay information preventing deduction of gate function from gate delay but allowing simulation of the integrated circuit with accurate propagation delay calculation. Individual gate delay values may be modified so that they obscure actual gate delays but so that the modified individual gate delays total to equal the actual cumulative gate delay along a given data propagation path.
