OPB bus design-based function verification platform construction method

Abstract

The invention provides an OPB bus design-based function verification platform construction method, and belongs to the technical field of IC design verification. According to the method, a script language and a hardware description language are used for building a verification platform. The method specifically comprises the following steps of: establishing a register information document accordingto an internal register of tested OPB bus design and parameters of a ram module; compiling an automatic scrip, generating, operating and controlling a test vector according to the register informationdocument by using the automation script, and adaptively adjusting the register with a special data processing process in the test vector; compiling an output information control script of the verification platform and an operation script of the verification platform through the automation script; and debugging and operating the test vector so as to build the verification platform. According to the method, the generation and operation of the test vector are automatically completed according to an internal register and ram module information document, a chip initialization control document andan arbitration module working manner description document by using the automation script.

Description

technical field [0001] The invention relates to the technical field of IC design verification, in particular to a method for building a function verification platform based on OPB bus design. Background technique [0002] At present, the rapid progress of integrated circuit manufacturing technology and the increasing market demand for highly integrated products have led to an exponential increase in the complexity of integrated circuits. As the complexity of integrated circuits increases, the difficulty of verification increases at a higher rate. Therefore, improving the realization ability of the verification work has become the focus and difficulty of the development of large-scale integrated circuits. [0003] Core connect is a bus specification for core+ASIC development or SoC design proposed by IBM, which can provide an efficient and complete connection method for the entire system. It includes three different bus types, namely the processor internal bus OPB (Process L...
