Abstract

The invention discloses a coverage-driven software and hardware cooperative SOPC function verification method and system. The method comprises the steps that firstly, according to SOPC software requirements, software function testing points are extracted, a testing requirement table is formed, and function testing points of the testing requirement table are extracted by using a Python script; secondly, the testing requirement table is converted by a software work station into testing vectors for testing data conversion logic and then sent to to-be-tested SOPC software; thirdly, the to-be-tested SOPC software in a hardware simulation accelerator outputs a signal, the signal is packetized through the testing data conversion logic and then sent to the software work station, and the software work station completes testing result comparison and functional coverage statistics; fourthly, the software work station marks unsanctioned function testing cases according to results of the testing result comparison, and executes uncovering function testing items according to results of the functional coverage statistics. By means of the coverage-driven software and hardware cooperative SOPC function verification method and system, the problem that an existing requirement-oriented manual testing method is low in testing efficiency is solved.

Description

technical field [0001] The invention relates to a SOPC function verification method for driving software and hardware coordination by coverage ratio. Background technique [0002] SOPC chips use a large number of intellectual property module IP multiplexing technology, including embedded CPU processors, and run embedded software at the same time, and have been widely used in aerospace, military and other fields. With the increasing scale of SOPC system chips, the adequacy of functional testing has become a major challenge in developing SOPCs. [0003] Existing SOPC system testing includes embedded soft-core application software testing and hardware logic testing. Embedded soft-core application software testing generally adopts a test method based on the combination of board-level functional testing and online debugging tools based on actual SOPC systems. Hardware logic testing methods Generally, the functional simulation test method based on the hardware HDL simulator is ad...
