Abstract

Disclosed is a method for applying input stimuli to electronic devices being used as Physical Models for a logic or fault simulation. Physical modelers today have a timing resolution defined by the maximum pattern apply rate which typically ranges from 40 to 600 nanoseconds. Consequently, all net changes within this interval will be merged into one pattern. If the Physical Modeler does not have skew time capability, all nets changing in the interval are applied simultaneously to the device. Those Physical Modelers that have a skew time adjustment always have a fixed skew time.
