Research on Failure Mode Prognostics of Digital Devices Based on IBIS Model

Application validation is an effective method for detection of aerospace components failure mode, Application of simulation based on the IBIS (Input/Output Buffer Information Specification) model can be failure mode prognostics of components. The application verification technical solution proposed in this paper completes the simulation of the application system environment, extracts the required data by carrying out PCB SI simulation in multiple simulation platforms based on the IBIS model, and then use software simulation and hardware co-simulation to achieve the application verification of the digital IC devices. this paper takes the application verification of SRAM as an example to discuss related technologies. Firstly, this paper conducts further studies on IBIS modeling techniques and completes the IBIS modeling work for SRAM, Secondly, PCB SI simulation based on IBIS models is carried out to simulate SRAM's board-level environments and data for the subsequent simulation is extracted. Finally, a software simulation platform and a hardware co-simulation platform are designed for the SRAM, and the application verification for SRAM is completed. The application verification of SRAM demonstrated the feasibility of the application verification simulation technical solution proposed in this paper.
