Problems solved by technology

In this process, the requirements for writing test stimuli are very high. At present, there is a lack of an effective method that can quickly and accurately describe test stimuli. The existing methods of writing test stimuli are mainly realized through programming and script files. These methods are greatly affected by external factors, have high requirements for writers, are time-consuming and labor-intensive, and are very difficult to understand and maintain, often resulting in verification work that cannot be completed on schedule

Embodiment

[0090] This method includes 10 kinds of simulation configuration commands and 14 kinds of chip configuration commands. Each configuration command is composed of command keywords and corresponding fields. (See attached table 1)

[0091] The simulation configuration command realizes the control of the simulation process. There are 10 commands in total. The format of each command is as follows:

[0092] The first command is to configure the simulation time command, the format is as follows:

[0093] SET_RUNTIME

[0094] The second command is the configuration waiting time command, which can be placed after any configuration command. When the program reads this command, it enters the timer and waits until the waiting time expires and starts to execute the next configuration command. The command format is as follows:

[0095] SET_COMMAND_WAIT

[0096] The third command is the configuration PCI command interval command, which can be used to specify the time interva...

Abstract

A method for describing PCI interface configuration stream in IC verification includes forming PCI interface configuration stream by a series of configuration command, using each command including 14 types of chip configuration command an 10 types of simulation configuration commands to make configuration access on assigned resource, automatically fetching and analyzing each field of vector text by configuration stream interpretive program in simulation to generate configuration command stream being transmitted to interface simulation module.

Description

Technical field [0001] The present invention relates to a function verification method in IC design, and mainly refers to a method for describing PCI interface configuration flow in IC verification. Background technique [0002] As the complexity and scale of IC design continue to expand, functional verification has become more and more complex. In the current IC design, 70% to 80% of the design cycle is spent on functional verification, so find a practical functional verification scheme, quickly and accurately establish a verification platform, and design appropriate tests for each functional point Incentives are an effective way to improve verification efficiency and shorten the design cycle. At this stage, the most widely used function verification method in IC design is that the designer enters the corresponding test stimulus according to the function description of the design specification document, and finds out the logic defects in the design through software simulation, a...
