Bisim is an event-driven, transistor-level, logic simulator that models both the logical and timing characteristics of custom emitter-coupled-logic/current-mode-logic circuits. Node voltages are represented by piecewise-linear waveforms, transistor currents are represented by piecewise-constant waveforms, and transistors are modeled as voltage-controlled current switches. Bisim's realistic circuit models enable it to simulate correctly a wide variety of circuit topologies while retaining much of the speed of higher level simulators. > |
