Mentor, Siemens Business Launches Automotive Electronic Systems Semiconductor Diagnostic Solution
Published2017.11.08 13:11Mentor, Siemens Business announced the launch of Tessent® MissionMode, a semiconductor test and diagnostic solution for automotive electronic systems.
Through the combination of automation capabilities and on-chip IP provided by this product, semiconductor chips across automotive electronic systems can be tested and diagnosed at any functional operating point of the vehicle. This is a fundamental capability in achieving the safety and long-term reliability requirements mandated by the ISO 26262 standard.
Tessent MissionMode is unique among commercial solutions in providing an infrastructure that enables access to any test and diagnostic functions integrated into automotive chips based on system software. The in-system test (IST) controller integrated in the chip drives an internal IEEE 1687 (IJTAG) access network to communicate with any IJTAG-compatible IP.
The IST controller particularly provides full support for all Tessent DFT (design-for-test) products, including memory BIST, logic BIST, and EDT logic. It also provides a communication path to the external world through a standard CPU interface. This interface can be easily adapted to operate with any CPU bus protocol commonly used in automotive systems, such as Ethernet, CAN, or I2C. The on-chip infrastructure features a high degree of programmability, allowing diverse test sequences to be applied as needed.
The Tessent MissionMode tool automates both the integration and full validation of this infrastructure, as well as the generation of all CPU instructions necessary to execute all tests and extract all diagnostic results.
Steve Pateras, Product Marketing Director for Mentor's automotive semiconductor test solutions division, stated, "The volume and complexity of electronic devices being designed to implement ADAS and autonomous driving capabilities in passenger vehicles is increasing exponentially." He added, "Through close collaboration with multiple customers, we continue to release new and innovative solutions that meet rapidly evolving automotive test requirements."

Mentor, TSMC CoWoS Packaging Technology Support
Mentor, a Siemens Business, announced that it has significantly enhanced its Calibre® nmPlatform, Analog FastSPICE™ (AFS™) Platform, Xpedition® Package Integrator, and Xpedition Package Designer tools to support TSMC's innovative InFO integrated fan-out advanced packaging and CoWoS (chip-on-wafer-on-substrate) packaging technology. Through TSMC's InFO and CoWoS 3D packaging technologies, customers can achieve higher levels of integration and capacity compared to traditional one-dimensional ICs by mixing multiple silicon dies into a single device. Mentor currently offers a comprehensive InFO verification and analysis suite spanning from design to package based on the Mentor Calibre and Xpedition platforms. Key benefits include a rapid hierarchical design prototyping environment in Xpedition Package Integrator that enables fast flow from design to tape-out, which is integrated into Xpedition Package Designer and Calibre sign-off verification suite. Through additional collaboration, cross-probing functionality between Calibre 3DSTACK and Xpedition tools has been expanded, and results can be reviewed within the Calibre RVE interface. TSMC and Mentor have also enabled Mentor's thermal analysis products (including Mentor AFS and Calibre xACT™ products) to support thermal-aware simulation for customers' InFO designs.
