Mixed-signal simulation by way of the Simbus backplane

This work discusses a simulation backplane called "Simbus", which allows analog and digital simulators to be connected and utilized together to perform mixed-signal simulation. The approach allows elements of the each domain to be expressed in their native format, simulate on their native simulators, and be coupled into an aggregate mixed-signal simulation. Currently supported simulators include the Savant VHDL simulator based on P. A. Wilsey et al. (see ibid., 1998) and Sandia National Lab's Xyce S. A. Hutchinson et al. (see ibid., 2002) simulator - a SPICE-like circuit simulator. Simbus is available under the open source LGPL license with source code freely available.
