Validation of an Automotive Ethernet Switch from FPGA to ASIC

Task:

Development and execution of an automotive Ethernet switch test process, which characterizes the switch for automotive applications during the prototype stage.

Content:

  • Definition of requirements and automotive use cases
  • Development of a test specification for specific ranges of conformity, performance and use cases
  • Alignment of the test specification contents to the architecture of the semiconductor to be tested
  • Quality check of the test coverage
  • Test process conversion to a highly automated test environment, for use in a test laboratory
  • Alignment of the test environment to semiconductor-specific characteristics, e.g. configuration management

Result:

  • Extensive test specifications with 100 percent test coverage of automotive-specific requirements. The test process supports OPEN ALLIANCE as a basis for the standard for qualifying electronic switches.
  • Successful validation of all stages of development, from FPGAs to turnkey ASICs.
