Method for describing Ethernet data flow in IC verification

Abstract

A method for describing Ethernet data stream in IC verification includes dividing Ethernet data stream to be eight structure blocks and using various structure blocks to describe information at data stream different layers, filling data required by data stream into relevant field of text in table-filling mode, automatically fetching and analyzing each field in vector text by vector interpretation program when simulation is carried out, generating various frame structures according to requirement, finalizing assembly of data stream and transmitting assembled data stream to interface simulation module.

Description

technical field [0001] The invention relates to a function verification method in IC design, and mainly refers to a method for describing Ethernet data flow in IC verification. Background technique [0002] With the continuous expansion of IC design complexity and scale, 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 out a feasible functional verification solution, quickly and accurately establish a verification platform, and design appropriate tests for each function point Incentives are an effective way to improve verification efficiency and shorten design cycles. The most widely used functional verification method in IC design at this stage is that the designer inputs the corresponding test stimulus according to the function description of the design specification document, finds out the logic defects in the design through software simulation, and finally ensu...

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
