Embodiment Construction

[0034] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0035] Such as figure 1 As shown, the main steps of VCD file and EVCD conversion are:

[0036]1. Read the pin information in the VCD file and EVCD file, analyze and process the pin information, and use the waveform viewer to determine the period.

[0037] 2. If the prefix or suffix that needs to remove the time-edge is defined, the waveform of the corresponding time length is removed before or after the entire waveform. This parameter takes effect in step 102 sub-step A.

[0038] 3. If the customer needs to remove some burrs (Jet, a burr refers to a short jump in a single cycle), then enter the proportion of the burr (that is, the proportion of the burr to the entire cycle), and select the Compare Mode (output mode) according to the need. Edge (along comparison) or Window (window comparison), choose whether to use repeat compression (repeat is a...

Abstract

The invention discloses a method of converting EDA (Electronic Document Authorization) files to ATE (Automatic Test Equipment) machine station format files. The method comprises the following steps of: processing (E) VCD (Video Compact Disc) format files in the EDA files by using a series of processing steps to produce WGL (Wingate License File) format files; and secondly converting the WGL format files and STIL (Standard Test Interface Language) format files in the EDA files to the ATE machine station format files by using a series of processing steps. According to the method disclosed by the invention, a special file processing technology is adopted, so that the conversion time is greatly reduced, wherein the WGL conversion time is about one third of a foreign product, so that a blank space of the field of national semiconductor testing is filled, and a new selection is supplied for enterprises needing the technical scheme of the invention, such as design companies and ATE manufacturers.

Description

technical field [0001] The invention relates to a conversion method of an ATE machine file, in particular to a conversion method capable of directly converting an EDA file to an ATE machine format file, and belongs to the technical field of semiconductor testing. Background technique [0002] EDA (Electronic Design Automation, electronic design automation) files have a variety of file formats, including VCD (Value Change Dump) file format, EVCD (Extended Value Change Dump) file format, WGL (Waveform Generation Language, waveform generation language) file format and STIL (Standard Test Interface Language, Standard Test Interface Language) file format. Among them, both VCD file and EVCD file are ASCII-based file formats, which are used to record signal information generated by EDA simulation tools. The formats between them are basically the same. The main difference between the two is that EVCD files have pins. Type information, that is, to mark the pin as an input pin or an ...
