Prediction Simulation Method for Analog/Mixed Signal Electronic Equipment Considering Soft and Hard Faults

Aiming at the problems that the reliability prediction simulation does not consider both soft faults (performance degradation) and hard faults (function failure) of devices, and the difficulty of simulation of Analog/Mixed Signal (AMS) circuits, this paper proposes a simulation method for reliability prediction of AMS electronic equipment. Considering soft faults and hard faults, the digital device model is established through the Hardware Description Language (HDL) model and the Input/Output Buffer Information Specification (IBIS) model, and the analog device model is established through the Hardware Description Language-Analog/Mixed Signal (HDL-AMS) model. Finally, the reliable life of the electronic equipment is obtained by analyzing the simulation results. This paper uses a typical AMS communication circuit as an example to demonstrate the practicability of the proposed method.
