JED2ADV Plus is a software package that translates a .JDL file (produced by the ACUGEN AADELAY TM software) into an Advantest pattern file. It also performs macro processing and position-independent data substitution on a user-supplied Advantest test program shell. The processed test program shell and pattern file verify PLDs for DC Parametric, Functional, and AC Parametric compliance. When JED2ADV Plus is used with the ACUGEN AADELAY and ATGEN® software and a user-supplied test program shell, PLD test program development for the Advantest T3319, T3320, T3340, or T3341 test system is truly automated.
JED2ADV Plus performs symbol substitution on a user-supplied test program shell (a test program with all variable data changed to symbol markers). The substitution process is very similar to a form letter generator -- JED2ADV Plus replaces each symbol marker in the test program shell with the symbol value (obtained from a parameter file), all other text is left unchanged. This technique provides a consistent test program format and allows a programmer to make changes to the test program shell -- a feature not available from hard-coded generators. A single test program shell can be used to test all PLD designs.
JED2ADV Plus also translates the .JDL file into an ASCII Advantest pattern file containing the test vectors necessary to functionally achieve the ATGEN-reported PLD fault coverage. JED2ADV Plus also creates AC Masks -- test vector sets containing only transitions with the same propagation delay time and stimulus (all other transitions are masked out).
JED2ADV Plus will typically translate a .JDL file into an Advantest pattern file and process a test program shell in under one minute when running on a 10Mhz IBM AT or compatible.
AC Parametric Testing
JED2ADV Plus creates as many AC Masks in the pattern file as required by the PLD design. The AC Masks provide a fast method of verifying a device's AC parametric compliance -- typically only requiring a few strobe settings using the MEAS LPAT statement. Worst-case AC parametric values can be obtained using a ASM TMEAS statement on the same AC Masks. The AC Mask technique is much simpler than trying to validate each transition's delay individually which could require hundreds or thousands of strobe settings and pattern passes.
All AC test limits are determined by the delay, phase, and settling time data obtained from the .JDL file. Using these limits, JED2ADV Plus can create AC parametric tests for PLD designs with complex feedback paths, I/O switching, etc., as effortlessly as AC parametric tests for simple PLD designs.
JED2ADV Plus produces a message file documenting the entire translation process. Each pattern file contains a header section that documents the translation process, test system requirements, test adaptor requirements, the input files, the programmer, as well as several lines of user-supplied comments. This information can be placed in the processed test program by using the appropriate symbol markers in the test program shell.
Unlimited PLD Support
JED2ADV Plus comes with approximately 100 ASCII parameter files for commercial and military PLDs. These parameter files contain the DC and AC parametric test conditions and DC parametric test limits for the PLD. Users can modify these files to meet their needs or create new parameter files using a text editor. JED2ADV Plus comes with detailed instructions on how to create your own parameter files for any PLD.
JED2ADV Plus uses an auto-configuration file to control the pattern file generation and test program shell processor. You can customize this file to your liking to establish the translation defaults. JED2ADV Plus has over 90 user-definable features. To simplify the handling of special situations, the auto-configuration file settings can be temporarily altered from the command line. New command line options can be added using the built-in preprocessor directives (#ifdef, #ifndef, etc.).
JED2ADV Plus is available for IBM compatible PCs running PCDOS or MSDOS, Sun 3 workstations running SunOS 4.0.3 or later, Sun SPARCstations and Sun 4 workstations running SunOS 4.1.1 or later, and VAX/VMS.
