Abstract: Based on the verification requirements and features of the PON structure FC_AE protocol chip,propose a simulation verification method which base on networking multi-RTL-model.Then,the paper presents the principle of test-case module,detector module and reference-model module.Build simulation environment to complete the simulation of the chip with this method.The verification method is based on the multilingual automated verification platform and support dual-channel authentication chip.Therefore,the efficiency of verification is effectively improved and the overall verification cycle is reduced,providing a reliable guarantee for the success tapeout of the chip.
