Automatic simulation testing method for HDLC protocol

Abstract

The invention discloses an automatic simulation testing method for an HDLC protocol. First, an automatic simulation testing system for the HDLC protocol is constructed. The system includes a testing frame data generating module (1), a frame format translating module (2), a C language based HDLC protocol gold model establishing module (3), an excitation and result database module (4), an indicatordetecting module (5) and a testing result display module (6). The testing frame data generating module (1) generates frame data for testing. The test data is translated into frame format data meetingthe HDLC protocol through the frame format translating module (2). The indicator detecting module (5) reads and detects output data of a to-be-detected module and a gold model at the same time and performs comparison. The comparison result is output and displayed by the testing result display module (6). The invention solves problem of long testing and verification time and comparatively low coverage rate of an HDLC module, can implement detection of different design indicators automatically and achieves quick and accurate positioning of hardware design problems.

Description

technical field [0001] The invention relates to a simulation test method, in particular to an automatic simulation test method for HDLC protocol. Background technique [0002] In the field of board-level communication of military electronic components, the HDLC protocol is a commonly used communication protocol. Many electronic devices contain HDLC communication modules. The quality of the HDLC module is directly related to the quality of the equipment. important. [0003] Due to the more or less modification of the HDLC protocol for each model task, and due to confidentiality reasons, each unit independently develops the HDLC communication module for its own model task, which causes multiple versions of the HDLC communication module to exist at the same time. The differences are small, but each version still needs to be thoroughly tested. [0004] At present, the traditional military HDLC module testing work only conducts a small amount of software simulation verifica...
