Food and Ontogenetic Shifts in Feeding of the Goosefish,Lophius Americanus

A behavioral design tool which is capable of designing circuits including high impedance buffers from hardware description language specifications. The design tool includes a behavioral synthesizer including a net expression routine, a high impedance structure and control expression routine (HI-Z routine) and a structure synthesis routine. The net expression routine reduces the hardware description language to net expressions which are analyzed by the HI-Z routine to look for high impedance states. If a high impedance state is found in a net expression the HI-Z routine develops the structure for an associated high impedance buffer and an associated high impedance control expression. The structure synthesis routine utilizes the net expressions, control expressions and high impedance buffers to develop circuits which realize the behavior described in the hardware description language.
