  We present a theoretical and a numerical formalism for analysis and design of
spintronic integrated circuits (SPINICs). The formalism encompasses a
generalized circuit theory for spintronic integrated circuits based on
nanomagnetic dynamics and spin transport. We propose an extension to the
Modified Nodal Analysis technique for the analysis of spin circuits based on
the recently developed spin conduction matrices. We demonstrate the
applicability of the framework using an example spin logic circuit described
using spin Netlists.
