VHDL Simulation of Magnetic Domain Wall Logic

The VHSIC hardware description language (VHDL) simulation of domain wall logic allows to validate magnetic circuits functionality early in the design stage. In this paper, we present two VHDL simulation techniques for domain wall (DW) logic. The first one, closer to the physics, uses models of components described at the behavioral level. It allows to study the basic functions and reveals the specificities of DW logic. The second one, closer to the logic, models components with logic gates and delays and it allows very fast simulation of complex circuits
