Patent ID: 8041552

Claim:
A method of modeling an output driver circuit, comprising: physically measuring at least one characteristic of the actual output driver circuit; and using the at least one characteristic to determine at least one parameter in a behavioral model in order to predict a behavior of the output driver circuit, the behavioral model based on a circuit comprising at least one output driver circuit having a differential amplifier including a first current source having a first current value and an emphasis driver including a second current source having a second current value; calibrating the first and second current values with accepted values; using the behavioral model to design target integrated circuits having at least one output driver circuit; wherein the modeling includes: modeling a voltage controlled voltage source section; modeling a capacitively loaded inverter section coupled to receive signals from the voltage controlled voltage source section; modeling a differential pre-amplifier section coupled to receive signals from the capacitively loaded inverter section; modeling a main differential driver coupled to receive signals from the differential preamplifier section; and modeling an emphasis driver coupled to receive signals from the differential pre-amplifier section and the main differential driver, wherein the at least one parameter determines a characteristic of the behavioral model.
