JED2HP82K+ is a software package that translates a .JDL file (produced by ACUGEN AADELAYTM software) into an HP 82000 vector file. JED2HP82K+ produces default pin configuration, levels, and timing setup files. It also performs macro processing and position-independent data substitution on a user-supplied HP 82000 test program shell and makefile. The processed test program shell and vector file verify PLDs for DC Parametric, Functional, and AC Parametric compliance. When JED2HP82K+ is used with the AADELAY and ATGEN® software products and a user-supplied test program shell, PLD test program development for the HP 82000 test system is truly automated.
JED2HP82K+ 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 -- JED2HP82K+ replaces each symbol marker in the test program shell with the symbols 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 alter 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. A sample C language test program shell is included to demonstrate the symbol substitution process.
JED2HP82K+ also translates the .JDL file into a binary HP82000 vector file containing the test vectors necessary to functionally achieve the ATGEN-reported PLD fault coverage. The vector file always utilizes the STD channel operational mode (25 mode for D50 systems; 100 mode for D100 and D200 systems) to ensure the availability of signal formats required by many PLD designs. JED2HP82K+ also creates AC Masks -- test vector sets containing only transitions with the same propagation delay time and stimulus (all other transitions are masked out) -- to support AC Parametrics.
JED2HP82K+ will typically translate a .JDL file into an HP 82000 vector file and process a test program shell in under one minute when running on a 10Mhz IBM AT or compatible.
AC Parametric Testing
JED2HP82K+ creates as many AC Masks in the vector file as required by the PLD design. The AC Masks provide a fast method of verifying a devices AC parametric compliance -- typically only requiring a few calls to the functional Standard Test Function. Worst-case AC parametric values can be obtained using the global_search Standard Test Function on the same AC Masks. The AC Mask technique is much simpler and faster than trying to validate each transitions delay individually which could require hundreds or thousands of strobe settings and vector pattern passes.
All AC test limits are determined by the delay, phase, and settling time data obtained from the .JDL file. Using these limits, JED2HP82K+ supports AC parametric testing for PLD designs with complex feedback paths, I/O switching, etc., as effortlessly as AC parametric tests for simple PLD designs.
JED2HP82K+ produces a message file documenting the entire translation process. A header section that documents the translation process, test system requirements, test adaptor requirements, the input files, the programmer, etc., can be placed in the processed test program by using the appropriate symbol markers in the test program shell.
Unlimited PLD Support
JED2HP82K+ 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. JED2HP82K+ comes with detailed instructions on how to create your own parameter files for any PLD.
JED2HP82K+ uses an auto-configuration file to control the vector file generation and test program shell processor. You can customize this file to your liking to establish the translation defaults. JED2HP82K+ 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.).
JED2HP82K+ 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, VAX/VMS and the HP9000 Series 700/HP-UX.
