Mentor Graphics Corp. has unveiled the Mentor Automotive Safety Certifiable Digital Instrument Cluster solution to allow safety-critical driver information to be displayed simultaneously with rich 3D graphics on a single instrument cluster display. According to the company, the software architecture features very fast boot time and is implemented on a multi-core and even on single-core SoC.

This solution addresses a key problem for the automotive OEMs: How to migrate safety-critical driver information to full-featured, graphically-rich digital instrument clusters and comply with safety standards including ISO 26262, without pushing up hardware or safety certification costs.

Automotive OEMs design digital instrument clusters that include graphical information relating to essential warnings from the vehicle such as icons notifying the driver of brake, engine or tire problems. The solution, which is compatible with safety-certified Nucleus RTOS and Mentor's automotive-qualified Linux solutions, allows safety-critical and non-critical information to be displayed simultaneously on the same display, while maintaining isolation of safety-related functions to comply with ISO 26262 safety standards. The low-overhead isolation features of the solution are uniquely designed to enable the most efficient use of system resources to allow maximum performance of rich 3D graphics, together with complex and demanding features such as infotainment, ADAS and smartphone connectivity, all driven from the same SoC, detailed the company.

The solution enables car makers to cut costs because the system is built on pre-certified components such as the Nucleus SafetyCert RTOS, resulting in reduction of the number of lines of new code to be safety certified. It reduces silicon cost because the solution runs on a single SoC, or even a single core, and makes efficient use of available CPU resources.

Mentor Automotive worked with Socionext Embedded Software Austria GmbH to integrate their CGI Studio development platform for automotive HMI with the Safety Certifiable Digital Instrument Cluster Solution.
