Interactive Command Language for OrCAD PSpice via Simulation Manager and its Utilization for Special Simulations in Electrical Engineering

The Interactive Command Language (ICL) significantly extends the simulation performance of several programs based on SPICE3 standard for the analysis of electrical networks in the so-called sequential mode, when the relatively independent tasks are run consecutively with a possibility of data exchange. However, the ICL is not implemented in the well-known OrCAD PSpice simulation program. The paper describes a conception of the so-called PSpice Simulation Manager (PSiM). This program implements the ICL in OrCad PSpice. PSiM is an independently executable program which controls the OrCad PSpice, enabling its operation in sequential mode. A powerful programming language also enables iterative runs within the conditional loops, which can be utilized e.g. for optimization. Concrete demonstrations of PSiM performance for circuit optimization and AC analysis of switched networks are included at the conclusion.
