  • Patent number: 4817012
    Abstract: In order to identify parasitic transistors in bipolar integrated circuit structures, files relating to the parameters of the simulated circuit are established. These files are then manipulated to establish the operating parameters of the simulated circuit. These operating parameters are then examined to identify the conditions that lead to circuit degradation due to parasitic transistors. The structure in the integrated circuit that result in the parasitic transistors are then highlighted on the circuit display in order to facilitate appropriate design changes.
