Method and apparatus for emulating interaction between application specific integrated circuit (asic) under development and target system.

摘要

An integrated circuit under development is tightly coupled to its target system such that the behaviors of the integrated circuit under development and the target system may be studied in real or pseudo-real time fashion. A pin dummy emulates the function of real pins on the yet-to-be-developed integrated circuit. A mirror relationship is established between cells of a real-pin register means and corresponding cells of virtual-pin nodes in the integrated circuit under development such that input signals presented at input ones of the real pins in the pin dummy are projected to input ones of virtual pins in the integrated circuit under development and further such that output levels of virtual-pins in the integrated circuit under development are projected to corresponding output ones of the real pins on the pin dummy.
