On Modeling And Simulation Technology For Nuclear Level FPGA Board

Aiming to solve probable problems of poor quality of transmissionsignal and low design specifications of high-speed system, this paperproposes a method of modeling and simulation of board based on softwareand hardware co-simulation technology, analyzes power integrity, signalintegrity and electro-magnetic compatibility as well as does simulation toguide and optimize the design of nuclear level system in order to increasethe stability and reliability of it. The study as follows:Firstly, emphasize the importance of power integrity for stable andreliable operation of system, and elaborate the essential reason of powerintegrity issues. Research modeling and simulation of power distributionnetwork of the nuclear level system, and propose reasonable methods tooptimize system design according to simulation results.Secondly, analyze influence caused by signal integrity issues includingreflection and crosstalk to signal transmission, do simulation of critical pathof system by IBIS models and cadence’s tool called SPECCTRAQuset.According to simulation results, propose the available measures andmethods to optimize the board design to meet requirements of signalintegrity.Thirdly, use analytical tool EMControl to analysis electro-magneticinterference strength of network, and EMIStream to check experience statute of entire board and to analyze resonance of power and ground planes as wellas do power supply pin decoupling analysis.Lastly, transfer HDL net-list to gate-level circuit structure, do simulationin PSpice, and establish correspondence between HDL and actual hardwarecircuit to realize software and hardware co-simulation and verification forFPGA.
