Abstract

Apparatus and method for detecting timing hazards which might be introduced in a pattern for execution on a tester when edges are improperly programmed in the pattern. The apparatus includes hazard detection circuits associated with the pins of the tester. Each circuit receives control inputs which specify which edges are involved in the hazard and limits on the permissible time between the specified edges. In operation, the pattern is executed repeatedly, once for each hazard which must be detected. The programmed times for the selected edge as well as the drive and format for each period of the pattern are variable inputs to the circuit.
