Technical Report Number
Lsim is a gate/switch level digital logic similar. It enables users to model digital circuits both at the gate and switch level and incorporates features that support investigation of the simulation task itself. This user's manual describes the procedures used to specify a circuit to lsim and control the simulation of the circuit (i.e., specifying inputs vectors, running the simulation, and monitoring output signals).
