Our BSDL Validation service verifies the accuracy of an integrated circuit’s BSDL file and eliminates a significant support issue for semiconductor suppliers.

Our clients are engineers responsible for designing, manufacturing and testing highly complex VLSI, ASIC, SOC, printed circuit board and system designs.

BSDL files describe the Boundary-Scan test functionality of an IC. To generate Boundary-Scan tests for an assembled PCB, every device on a Boundary-Scan chain on the board must have an accurate BSDL file. The accurate BSDL files shorten the time-to-market for the OEM’s products, because this reduces the cost of test and simplifies manufacturing.

We validate the accuracy of an integrated circuit's Boundary-Scan description language (BSDL) file. The BSDL Validation service goes well beyond the mere checking of the syntax and semantics of a BSDL file.

The StarTest personnel will perform PRELOAD/EXTEST instructions for each I/O of your device to verify the accuracy of the contents of the BSDL file and to validate that all Boundary-Scan cells of each such I/O are working properly. The set of Boundary-Scan tests are generated from the device’s BSDL file, and these tests are run on the device to validate that the BSDL file exactly matches the features implemented in silicon. If any anomalies are found, the BSDL file is corrected and the device is re-tested.

We trust you will find it helpful in improving the quality of your BSDL files and silicon. Our service can quickly spot JTAG insertion and BSDL errors and is an excellent way to prevent Boundary-Scan testability problems in the field. We will generate a test sequence for your device and BSDL consisting of:

• TAP Reset (both hard with /TRST and soft)
• EXTEST Pin Test (per I/O pin)
• Instruction Register (IR) Capture Test
• Bypass Register (BYP) Test
• Boundary-Scan Register (BSR) Length Check
• IDCODE Reading Verification
• USERCODE Check (if applicable)
