Key Features

In-System Test and Diagnosis of Automotive ICs

Tessent MissionMode is the only commercial solution that provides the infrastructure for system software-based access to any test and diagnosis capabilities integrated within an automotive chip.

Flexible In-System Test Architecture

Tessent MissionMode provides system-level low latency access to all on-chip test resources for on-line test and diagnosis. The hierarchical network of scan insertion bit switches allows for communication to the distributed test resources. An IEEE 1149.1 test access port provides external access to the IJTAG network.

Real-Time Test Control

The Tessent MissionMode controller can be configured to operate in two different modes. In CPU access mode, the controller supports parallel read and write operations to and from a CPU bus. In the direct memory access (DMA) mode, the Tessent MissionMode controller reads command data preloaded in a non-volatile memory such as a ROM.

ISO 26262 ASIL Certified

Tessent MissionMode is delivered with an ISO 26262 software tool qualification report that provides the required evidence of the tool’s suitability for ISO 26262 related tasks. The report can be used to simplify the ASIL device certification process significantly. All Tessent software tool qualification reports are certified by SGS-TüV Saar.
