Abstract

The invention relates to a virtual verification system and method based on an AFDX network switch chip. The virtual verification system comprises a top level and a test item library, the top level comprises a virtual excitation sequence, a verification environment and interfaces, and the verification environment comprises three or more Ethernet interface modules, a host module and a scoring plate. The virtual verification system and method solve the problem that an existing directional testing virtual verification system and method cannot complete the verification of the AFDX network switch chip, and competition of a design and a model in the simulation process is removed. The read-write operation of an external function model and the read-write operation on a port signal wire are segregated, development and maintenance are easy, and the developing complexity is lowered.

Description

technical field [0001] The invention belongs to the field of integrated circuit verification, and relates to a virtual verification system and method for AFDX network switch chips based on random control. Background technique [0002] The transmission of information between aviation subsystems is the most important part of the airborne system, and the electronic system is currently the best way to transmit data. Avionics Full Duplex Switched Ethernet (AFDX) is an electrical and protocol standard developed for data exchange between avionics systems. It builds on the AFDX concept introduced by Airbus and is 1000 times faster than its predecessor, the ARINC 429. AFDX network consists of avionics system, AFDX terminal system and AFDX switch. [0003] Since the AFDX network redefines a set of communication protocol standards based on the standard Ethernet transmission protocol, the AFDX switch chip needs to have features such as AFDX traffic police management and filtering.
