Infineon adds support for AutoSAR v4.4.0 to Aurix software

Tue, Jun 06, 2023

Support for AutoSARv4.4.0 extend the Aurix TC3xx MCAL support already available from Infineon Technologies. This expansion adds ASIL D and SIL-2 compliant drivers to support AUTOSARv4.4.0.

For ASIL D applications, the MC-ISAR TC3xx roadmap has been updated to also provide ASIL D compliant drivers. With the upcoming Maintenance Release 2.25.0, the driver will include ASIL D compliant software products. Support for IEC 61508 SIL-2 will be provided with Release 2.30.0. The latest release aims at AutoSAR applications in all automotive domains, including engine, chassis, safety, and body. It also applies to commercial agricultural vehicles (CAV), industrial and marine applications, Infineon noted.

According to the company, the biggest advantage of the MC-ISAR AS440 EXT TC3xx is its support for the latest standards, eliminating the need for additional drivers for ASIL D argumentation. It facilitates software partitioning and provides more flexibility by allowing the driver to run in an ASIL D domain, simplifying system-level security argumentation. Developers can therefore work with a production-ready driver with a qualification and safety certification that is ASIL D compliant, helping to avoid systematic failures. In addition, the driver offers ISO 21434 support for continuous monitoring.

Infineon’s partners further assist developers with additional services and support.

The listed AutoSARv4.4.0 MCAL software packages is provided with MC-ISAR Basic drivers enabled (MCU,DIO, ICU, GPT, PWM , SPI , ADC, WDG, OCU, FLS, FEE, CAN, CanTrcv, LIN, BFX, CRC).

Another driver is the MC-ISAR Com Enhanced (FlexRay, Ethernet). Infineon also provides the MC-ISAR MCD MCAL complex driver – 11 complex drivers in addition to the standard AutoSAR drivers (DMA, FLSloader, UART, DS-ADC, SMU Safety Management Unit, DEMOCD: HSSL, SENT, I²C, IOM I/O Monitoring, STM System Timer, IRQ Interrupt Request).

In addition, the software packages include important features like AutoSAR BFX and CRC library, ASPICE L2, ASIL D process for FFI, MISRA 2012 change 1 (CERT-C) compliance (AUTOSARv4.4.0), and ISO 21434 support for continuous monitoring.

The key ASIL D compliant drivers with IEC 61508 SIL-2 support will be available from mid-2023.

u-blox and Tallysman Wireless collaborate on augmented smart antennas

Mon, Jun 05, 2023

As part of a design partnership between u-blox and Tallysman Wireless, the ZED-F9R GNSS and NEO-D9S L-band receivers will be integrated with Tallysman’s Accutenna technology in the next generation PointPerfect augmented smart GNSS PPP-RTK augmented smart antennas.

The PointPerfect GNSS augmentation service is now available in North America, Europe, and parts of Asia Pacific.

“The TW5390 solution offers users high-precision with rapid convergence times, access to precise, reliable, and easy to use PointPerfect PPP-RTK GNSS augmentation data. The result is centimetre-level accuracy in seconds on a continental scale for exceptional precision,” said Christopher Russell, Tallysman’s vice president of sales. The design partners expect to integrate the antenna and receiver technologies

The multi-band (L1/L2 or L1/L5) architecture removes ionospheric errors and the multi-stage enhanced XF filtering improves noise immunity while relying on the dual feed Tallysman Accutenna element mitigates multi-path signal interference rejection. Some versions of the smart antenna solutions include an inertial measurement unit (IMU) for dead reckoning and an integrated L-band corrections receiver to ensure operation beyond terrestrial network reach.

“Tallysman and u-blox offer a turnkey silicon-to-cloud solution since PointPerfect is already pre-integrated with u-blox ZED-F9R and NEO-D9S high-precision GNSS modules. Our intuitive cloud platform provides a self-serve environment from which users have autonomy to manage IoT device fleets. This eliminates complexities and allows users to engage more efficiently and reduce time-to-market,” said Franco de Lorenzo, principal product owner, services at u-blox.

Lidar target simulator extends Keysight’s autonomous driving test portfolio

Mon, Jun 05, 2023

Automated testing software provides insightful analytics to improve sensor design and performance, said Keysight Technologies. The company has expanded its portfolio of autonomous driving validation test products with the E8717A lidar target simulator (LTS), which enables automakers and lidar sensor makers to test and validate lidar sensors for autonomous vehicles (AVs).

Initially developed for use in meteorology and topography, lidar is now being adopted as an automotive sensing technology that enables AVs to “see” and safely navigate through complex driving scenarios. Lidar sensor makers must ensure advanced driver assistance systems (ADAS) quickly and reliably detect objects. To properly test sensors, designers currently need large floor spaces and use traditional target boards. There is also industrial pressures to reduce sensor cost and scale to mass production, said Keysight.

The Keysight LTS addresses these challenges by simulating test targets at defined distances and reflectivity with a compact and standardised bench setup. It is designed to simplify and accelerate the testing, validation and production of automotive lidar sensors through standardisation and automation.

The compact bench setup saves test floor space by simulating target distances from three to 300 metres and simulating surface reflectivity from 10 to 94 per cent.

The testing software generates insightful analytics by sweeping target distance and reflectivity. This enables the design and performance of sensors to be improved, said Keysight.

The LTS test setup is fully automated using a cobot and powered by Keysight PathWave Test Executive for Manufacturing for test automation. The cobot provides precise device movement for field of view testing and the automation software accelerates testing and throughput to support volume production.

According to Thomas Goetzl, vice president and general manager for Keysight’s Automotive and Energy Solutions, this is the first cobot-assisted lidar target simulator with variable distance and reflectivity simulation available and enables the company to “support a volume roll out of lidar with a scalable manufacturing test solution.”

Keysight will demonstrate the E8717A LTS at Automotive Testing Expo Europe 2023 in Stuttgart, Germany (13 to 15 June) Hall 10-1332.
