Taking concepts from advanced pre-silicon verification methodologies (e.g., UVM) and applying them to a hardware tester validation platform (i.e., AVE) delivers unprecedented control over all aspects of hardware testing, especially high- speed interfaces. As technology progresses, we expect to see more and more devices in the market with different types of high-speed interfaces.
This breakthrough approach enables, for the first time, complete testing that includes high-speed interfaces. It gives developers and manufacturers a much higher degree of certainty in the correctness and safety of their complex electronic devices.
DO-254 expects developers to use their best effort to validate their designs. There is no absolute definition of what is a “good enough” effort. In the absence of absolute proof, you need to invest much time and energy to show that what you have done is as good as technically possible.
