MATLAB - SPICE interface (MATSPICE) and its applications

This paper introduces an interface between MATLAB and SPICE, some of its applications will be introduced and examples on these applications will be illustrated. This interface allows the circuit designer to use all the benefits of the circuit level simulators under the MATLAB environment. This avoids many manual steps done on the simulator. Simulation results are transferred to MATLAB to be analyzed using the powerful MATLAB toolboxes. The scope of the applications of MATSPICE is huge and depends on the circuit designer. The applications in this paper will be in the circuit sizing and in the automatic verification of MATLAB circuit and device models. MATSPICE can be a part of a more general synthesis tool as will be shown in the examples.
