Automatic error pattern generation for design error detection in a design validation simulation system

Considering the fact that simulation patterns can detect a different number of design errors, the derivation of efficient simulation patterns is important. Automatic error pattern generation is introduced to generate a set of error simulation pattern which can be used as input stimuli for design error simulation, a design validation tool which provides a measure of simulation coverage. These tools provide a solution to a long standing problem that has limited design options and design cycle time. They also can decrease design and testing costs
