Abstract

Disclosed is a simulation model which facilitates the 'real-time' simulation of application specific integrated circuits (ASICs) in the actual digital computer system in which they will be incorporated. Significantly, this invention permits the emulation of an ASIC device, and thus does not require the fabrication of an actual physical specimen of that device. Instead, this invention permits the use of a software model which facilitates debugging of the ASIC device and permits effective generation of system test vectors. Such an approach facilitates the system-level testing of ASIC devices prior to fabrication, by permitting both the generation of system test vectors and the debugging of the internal behavior of such ASIC devices without limiting the flexibility, with respect to other devices in the system, of either simulating such devices in software or utilizing actual physical specimens of such devices.
