ABSTRACT:
Method and system are disclosed for modeling dynamic behavior of a transistor. The method includes representing static behavior of a transistor using a lookup table, selecting an instance of the transistor from the lookup table for modeling dynamic behavior of the transistor, computing a previous state of the instance using a non-quasi static analytical model, computing a variation in channel charge of the instance according to a rate of change in time, computing a current state of the instance using the previous state and the variation in channel charge, computing a modified terminal voltage that includes a dynamic voltage across a parasitic resistance at the terminal of the transistor according to the current state and previous state of the instance, and storing the modified terminal voltage in a memory device for modeling dynamic behavior of the transistor at the current state.
