Abstract

The invention discloses microprocessor function verifying equipment. The equipment comprises an instruction set simulator, a comparator, a monitor, an input interface and an RTL (Register Transfer Language) module, wherein the instruction set simulator is used for executing a test program and generating a periodical reference data file; the comparator is used for reading the periodical reference data file from the instruction set simulator; the input interface is used for loading the test program into a memory cell of a to-be-verified design; the monitor is used for capturing a to-be-verified signal in to-be-verified design simulation and outputting to the comparator; the comparator is used for comparing whether reference data in the periodical reference data file is consistent with the to-be-verified signal or not; and the RTL module is used for reading part internal signals of the to-be-verified design from the to-be-verified design cycle by cycle to decide whether the behavior of the to-be-verified design is consistent with the behavior of the RTL module or not. The equipment disclosed by the invention has the advantages that the technical problem that the function inspecting efficiency of the to-be-verified design is low in the prior art is effectively solved, so that the efficient and fast function inspection is realized and the verifying efficiency is increased eventually.

Description

technical field [0001] The invention relates to the technical field of integrated circuit development, in particular to a microprocessor function verification device and a microprocessor function verification method. Background technique [0002] With the rapid development of electronic information technology, the degree of informatization of human society is constantly improving. The exponential growth trend of integrated circuit technology, which is the basis of electronic information technology, is one of the important driving forces for the rapid growth of electronic information technology. According to the forecast report of the International Semiconductor Technology Roadmap, from 2013 to 2026, the integration of microprocessors and high-performance ASICs will still double at a rate of three years. However, the integrated circuit verification capability, which is seriously lagging behind the design and manufacturing capabilities, will encounter unprecedented challenges....
