ABSTRACT:
An emulator for non-fixed instruction set VLSI devices having a microprogrammable emulator controller which can be used with a variety of VLSI devices and provide in-circuit emulation for general VLSI technology with capabilities comparable to the in-channel emulation capabilities previously available for fixed instruction set MOS microprocessors. This includes a device specific emulator head which is controlled by the emulator controller to emulate a VLSI device in a target machine. The VLSI device to be emulated is removed from the target machine and a device plug of the emulator head is inserted into the target machine. The VLSI device is placed in a socket in the emulator head. The emulator controller monitors instructions sent from the target machine to the VLSI device and provides instructions to the VLSI device.
