VHDL-based distributed fault simulation using SAVANT

Abstract

There is a need for simulator-independent, VHDL-based fault simulation. Existing techniques for VHDL-based fault simulation are reviewed. Robust, a simulator-independent fault simulator tool, is described. Slow simulation speed is identified as one limitation of the current Robust tool and distributed simulation on a network of workstations is identified as a feasible way to improve its performance. Previous network-of-workstations fault simulation experiments are reviewed. Current efforts to enhance the Robust tool using SAVANT ate described. A system using Robust (with SAVANT extensions) for fault simulation on a network of workstations is proposed, using the TyVIS VHDL simulation kernel and the Legion distributed processing system.
