Abstract

A method of generating a circuit design comprising a T-coil network includes determining inductance for inductors and a parasitic bridge capacitance of the T-coil network. The parasitic bridge capacitance is compared with a load capacitance metric that depends upon parasitic capacitance of a load coupled to an output of the T-coil network. An amount of electrostatic discharge (ESD) protection of the circuit design that is coupled to the output of the T-coil network and/or a parameter of the inductors of the T-coil network is selectively adjusted according to the comparison. The circuit design, which can specify inductance of the inductors, the amount of ESD protection, and/or the width of windings of the inductors, is outputted.
