VectorPort is a test development tool for converting WGL or STIL test vectors into targeted, production ATE test patterns. VectorPort enables you to quickly generate patterns, pinmaps, and timing data; easily turn Scan ATPG files into production-ready tests; add or remove signals, modify timing, and more with the graphical pin and timing editors; and view signal waveforms and timing relationships with the WGL and STIL waveform viewer. ATE-specific options allow for smooth integration with your test development environment, including the NI-Digital Pattern Driver or Digital Pattern Editor for use with PXI Digital Pattern Instruments and the NI Semiconductor Test System (STS)..
Use the graphical interface to select, edit, and configure the conversion process or select the command-line interface for scripting and batch processing. The push-button conversion process requires little or no training and has been optimized for speed and low memory usage. Get pattern conversion statistics such as the number of vectors processed, compression ratios, scan chain and vector counts, and more.
VectorPort accepts WGL and STIL formatted test vectors and can convert parallel and serial SCAN vectors from many widely used ATPG tools, including FastScan and TetraMax. It also allows you to import and edit large, broadside functional test vectors quickly and easily as well as select several files at once and process them all with one click with batch-mode processing.
Generate patterns, timing, pinmaps and more for PXI Digital Pattern Instruments and NI STS. Each output writer has tester-specific options to ensure seamless integration and to enable and utilize important tester features and functions. Convert your STIL or WGL test vectors to VCD or EVCD using VectorPort and verify your test vectors in the design environment.
You can quickly convert your scan test vectors to production ATE patterns with VectorPort, and easily normalize different length scan chains and edit scan signal formats and timing in VectorPort. Additionally use VectorPort to automatically verify and condition scan vectors to ensure they meet the requirements of the target ATE platform. Also flatten scan-formatted vectors into normal, broadside test vectors and run on non-scan equipped ATEs (no ATE scan license required).
VectorPort has several tools to help generate your ATE test vectors. You can edit existing pins and signals in your STIL and WGL vectors or add new ones using the Signal Editor; modify edges and formats or create new timing sets using the Timing Editor; and visualize your WGL and STIL test vectors in a logic-analyzer format with the graphical Waveform Viewer. Save modified signal and timing sessions and reuse them with other, similar pattern conversion projects.
VectorPro is a test development tool for generating cyclized ATE test vectors in either WGL or STIL formats. This versatile and easy to use tool reads in both VCD and EVCD formatted design simulations, and using the feature rich GUI, users are able to view and modify the simulation to fit the needs of their test environment. VectorPro supports multiple timesets, event conditioning, histograms of signal edges, automated timing generation and batch mode operation. In addition, the waveform viewer allows users to easily navigate across simulations to find areas of interest.
NOTE: VectorPort and VectorPro are separately licensed tools. VectorPro is designed to read design simulation files and generate cyclized test patterns (VCD/EVCD » WGL/STIL). VectorPort is designed to read cyclized test patterns and generate tester-specific test patterns (WGL/STIL » NI Digital Patterns).
TD-ScanPro™ is TSSI's next generation test pattern tool to convert WGL, STIL, VCD, or EVCD files for use with NI Digital Instruments. TD-ScanPro can generate the files required for NI Digital Pattern Instruments as well as NI Digital Waveform Instruments.
The advantages of TD-ScanPro™ are:
Using the graphical user interface (GUI) or batch mode to get the job done quickly, TD-Sim and TD-Scan provide an easy-to-use, fill-in-the-blank form to import and generate target tester's output quickly. No manual or instructions are needed for new/casual users.
Advanced/heavy users can use batch mode to queue numerous conversion processes.
All of the graphical user interface components mentioned above can be saved as an ASCII file if scripting and batch processing are preferred.
All documentation is available under the Help menu with hyperlinks for easy navigation.
Each WGL, STIL, VCD, or EVCD format is a corresponding In-Convertor. For example, to read a scan ATPG file in IEEE STIL format, a TD-ScanPro “STIL In-Convertor” operation can be placed into the Scenario Canvas and connected to the source file’s icon.
The reading process will neutralize different EDA format into a binary ATE-neutral, compact database (“SDB”), which can be viewed, modified, or programmatically access via the SDB API (very favorable by companies with proprietary tools and methodology).
From the SDB database, the user can choose a target ATE platform.
TD-Sim and TD-Scan translate EDA files into an intermediate database. Any subsequent data analysis and adjustment can be done directly to the database using the waveform viewer. Then, when ready, the TestBridge can be invoked to generate tester-ready patterns. For large patterns, this will save many conversion hours.
TD-Sim and TD-Scan Signal Table enables familiar spreadsheet format for pin mapping and a wide variety of operations on signals such as: synthetic signal derivation, setting of levels, ATE specific pin modes, pin groups, and import/export.
TD-ScanPro inherits more than 3 decades worth of test development tools known as the Conditioners from TSSI’s pioneering effort in various aspects of design-to-test technologies. Any test data manipulation tools needed over the years are available especially for converting VCD/EVCD into the NI platform.
Some popular conditioners are: GuardBand, Min/Max, Pattern edit/cut/merge, Strobe Edit, Signal Edit, Scan Flatten, Incremental, Waveform Analysis, Histogram, etc.
TD-ScanPro simplifies processing of hundreds of pattern files by an intuitive Loop Object in the Scenario Canvas. Loop Object iterates through all input files specified by the user’s rule (e.g., *.wgl, atpg/src*.stil, simulation/*.evcd) and convert them all to a target ATE format.
Utilizing the Incremental Conditioner’s capability, the Loop Object can accumulate timing and only generate timesets that have not been seen before and therefore, produces an optimized master timing file that serves all patterns.
This code converts HWS, text, or binary files generated by the NI Digital Waveform Editor to .digipat and .digipatsrc files. The .digipat files can be directly opened with the NI Digital Pattern Editor for debug and/or modification. This converter also produces a .pinmap file and a .digitiming file, consisting of a single time set equal to your original waveform's sample rate with all pins defined as non-return.
