The challenge
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.
