Hardware Modeler Replacement for Digital Device Simulation

Many custom and hybrid integrated circuits (ICs) and custom electronic components cannot be modeled in simulation software because of their complexity and/or lack of technical data. The current hardware modeler (D300) in conjunction with the Teradyne LASAR digital simulator has the ability to perform this modeling. The hardware modeling system has the ability to model multiple devices (both dynamic and static devices) simultaneously. It is also able to retain input (stimulus) and output patterns for entire clock cycles, and therefore, reestablish the state of the device under simulation in a repeatable manner. WesTest proposes using of the VDATS Di-Series digital subsystem hardware as a replacement for the D300 hardware. WesTest shall develop a solution that can replace the Teradyne D300 DATASource Hardware Modeler with the WesTest D3000 DEVICESource Hardware Modeler System which utilizes the VDATS TERADYNE Di-digital subsystem hardware. The new WesTest D3000 DEVICESource Hardware Modeler System will replace the obsolete D300. This concept solution addresses software interfaces, hardware interfaces and estimates of LASAR simulation run times using the VDATS Di digital subsystem hardware. Also, the solution includes the device/chip socket concepts, the device hardware model file concepts, LASAR devise model files, receiver interface, pin-map layout. etc.
