A MAPLE-based homotopic circuit simulation package

This work presents HomotopyDC, a package that carries out the DC analysis of a circuit by using homotopy methods, i.e. methods that are able to find more than one DC solution. The capabilities of MAPLE have been used to their full extent in order to formulate the equilibrium equation of the circuit in a fully symbolic form, which is then used to formulate the homotopic equation. Not only are the DC solutions calculated, but also their stability is assessed. Several homotopy schemes have been implemented within the package.
