The invention comprises a method and system for encoding and generating transaction-based stimuli event states for the eventual application to the simulation of VLSI circuits. The assembly further includes a protrusion located on one of the housing or the cover, and a track located on the other one of the housing or the cover. Each section comprises a plurality of data input lines for receiving data signals from the image input lines. The first and second mounting members are, for example, a number of first resilient legs and a number of second resilient legs, respectively, each of which is structured to bias a corresponding one of the lateral protrusions into engagement with one of the coupling elements of the panel member.
