Checker, function verification system and method based on serdes protocol verification

Abstract

The invention provides a checker based on SERDES protocol verification and a functional verification system and method. The checker comprises a design module to be checked, an instruction receiving and sending module for sending instructions, a decoding module for decoding a coded data stream to be checked, a storage module for storing non-coded data, and a check module for reading the non-coded data and conducting functional verification. The method includes the steps that a data stream to be checked is received, if the data stream is coded data, decoding is conducted to obtain non-coded data and control word information contained in the code stream is output, and if the data stream is non-coded data, the data stream is directly received; the non-coded data is stored; the non-coded data is read, and functional verification is conducted on the non-coded data according to an external instruction. The checker can be reused in the data output port of any design module to be checked, supports verification of various code stream sequences or data packages in different frame formats and supports verification of coded / non-coded functional modules, the verification flexibility and different-design reusability are improved, the cost is reduced, and the function coverage of verification is increased.

Description

technical field [0001] The invention relates to the field of integrated circuit function verification, in particular to a SERDES protocol-based verification checker, function verification system and method. Background technique [0002] The scale and complexity of integrated circuit design continue to increase. In the context of industrial development, the importance of verification is becoming increasingly prominent, and the requirements are getting higher and higher. Most of the IC design cycle is placed on functional verification, ensuring high verification coverage while reducing verification time has become a bottleneck in IC design. At present, based on SerDes (SERializer / DESerializer, serial deserialization communication) technology, the industry has introduced a variety of high-speed serial interface standards: such as PCIe, SATA, HDMI, USB3.0, RapidIO, XAUI and MIPI. In the process of functional verification of these protocol interface modules, in order to ensure t...
