Digital systems must be reliable, maintainable, and verifiable. High-quality testing and testable design reduce defects, shorten time-to-market, and lower long-term maintenance costs. Below is a concise, structured text you can use as a section in documentation, a whitepaper, or a technical guide.
A complete testing solution combines several high-level strategies to ensure maximum fault coverage with minimal hardware overhead. Digital Systems Testing And Testable Design Solutions A defect may only fail when domain A is at 0
: Contrast deterministic methods like the D-algorithm, PODEM, and FAN with genetic algorithms used for complex sequential circuits. Digital systems must be reliable
Modern chips have 10+ voltage islands. A defect may only fail when domain A is at 0.8V and domain B is at 1.2V. DFT must handle and isolation cells correctly. Testing requires sequencing of power-up/down within the test flow. or a technical guide.
