TSSI Demonstrates Time Saving WaveMakerPLUS and Protocol Integrator Supporting IJTAG Standard in Solstice™ pdf

ANAHEIM, Calif., -- September 10, 2013 -- Test Systems Strategies, Inc. (TSSI), a world leader in test pattern conversion and validation tools today showcased two new major product capabilities based on TSSI's next generation tool platform: SolsticeTM. First is WaveMakerPLUS, a pre-silicon pattern validation interface enabling design and test teams to work within the same environment. The other capability is a protocol integrator which supports the new IEEE P1687 IJTAG standard. Both capabilities were demonstrated on the ITC 2013 exhibit floor held in Disneyland Hotel, Anaheim California from September 10 to 12, 2013.

Solstice WaveMakerPLUS - Demonstrating significant progress advancing pre-silicon pattern validation and debug enabling faster patterns bring-up

Solstice accepts all Scan, Built-In Self-Test (BIST) and functional patterns to validate with the designer's DUT model for advanced preparation of test patterns enabling the earliest detection of problems that would cost millions of dollars if they slipped through tape-out into mask and silicon manufacturing processes. TSSI today demonstrated the Solstice WaveMakerPLUS that will lead to a >50% improvement in design-to-test productivity.

Compile-Once-Simulate-Many enables Failure Analysis On-the-Fly

Solstice's seamless integration with leading logic simulators and preservation of design and test data enables, as the simulation progresses, immediate graphical viewing of discrepancies between the expected state with that of the DUT model response. Solstice's robust WaveMakerPLUS shows strobe placement and type, the nature of failure, and correlation to the scan register instance. Customers saw the ease of modifying waveforms, making mask changes coupled with local and global timing changes – all with single mouse clicks. Following waveforms modifications, the simulation re-executes immediately - without the need for re-compilation of the Verilog testbench, re-translation or text file editing - enabling fast and precise validation of the revised vector set.

The demonstration explored the different challenges and solutions demanded by the most complex and advanced device architectures and how vector sets can be validated by the DFT teams before handing over to the test team.

WaveMakerPLUS can import/export STDF and simulator’s diagnostic files to work with customer’s existing failure analysis flow.

Solstice Protocol Integrator – Demonstrating the supports of IJTAG (IEEE P1687) Standard 

The emerging IEEE P1687 standard provides designers with a consistent approach to integrate multiple scan chains, BIST engines and on-chip instrumentation. The purpose of the IJTAG initiative is to provide an extension to the IEEE 1149.1 (JTAG) standard specifically aimed at using the Test Access Port (TAP) to manage the configuration, operation, and collection of data from the embedded circuitry. The IJTAG standard establishes a methodology to access embedded instrumentation or cores via the IEEE 1149.1 Test Access Port (TAP) with additional signals as required.

The demonstration showed how Solstice Protocol Integrator accepting the IJTAG description language files (ICL and PDL) that describe the characteristics and communication methodology, creating a complete wavefom set to be used for Solstice Pattern Validation or incorporated within a test program using TSSI’s extensive TesterBridge offerings.
