Design and test of certifiable ASICs for safety-critical gas burner control

The purpose of this paper is to present a methodology and tools for the design and test of a EN298 compliant ASIC chip for safety-critical gas burner control, Safe operation, as far as the critical variable is concerned, is guaranteed in the presence of two simultaneous bridging or open defects. Emphasis is put on circumventing methodology, EDA (electronic design automation) and foundry limitations and on product certification requirements.
