Global semiconductor manufacturer designing semiconductors and software for mobile communications, consumer electronics, security applications, in-car entertainment, and networking. It also offers its products to the automotive, identification, wireless infrastructure, lighting, mobile, and computing applications.
Silicon wafer production required an easy way of detecting and rejecting damaged chips at the earliest possible stage. A built-in ROM test framework allows for chip testing in the factory, with the use of test inbuilt-in the system.
What we did
Built-in chip (ROM) test framework design:
- specification of requirements,
- architectural design,
- design of security features.
Built-in chip (ROM) test framework development:
- virgin device handling
- secure card code loading to RAM and NVM
- built-in chip test procedures (ROM)
- wired communication
- security features using symetric & asymetric primitives.
Built-in chip (ROM) test framework validation:
- test plan specification,
- test specification,
- test implementation,
- automated testing.
