SpinSPICE (published to arXiv and IEEE TCAS) allows complex spintronic circuit design for memory and logic. Here are some very detailed model descriptions.
Modeling MRAM with spin-spice with stochastic variations (JAP).
Fokker-Planck models of magnetic switching.
Circuit models for Qubits :
This model generates coupled electronic qubit performance. The model can be combined with spinSPICE.
Silicon photonics :
Electro-optic simulations of modulators
Time domain simulation of micro-ring resonators
Device geometry optimization of carrier injection modulators
Test setup for high-speed measurements
