Lessons Learned – Voltage & Temperature Margin Testing
Year: 2000
Abstract: Practice:
Voltage and Temperature Margin Testing (VTMT) is the practice of exceeding the expected flight limits of voltage, temperature, and frequency to simulate the worst case functional performance, including effects of radiation and operating life parameter variations on component parts. For programs subject to severe cost or schedule constraints, VTMT has proven an acceptable alternative to conventional techniques such as worst case analysis (WCA). WCA is the preferred approach to design reliability, but VTMT is a viable alternative for flight projects where trade-offs of risk versus development time and cost are appropriate.
