Abstract

A high-level synthesis approach is proposed for design of semi-concurrently self-checking devices; attention is focussed on data path design. After identifying the reference architecture against which cost and performances should be evaluated, a simultaneous scheduling-and-allocation algorithm is presented, allowing resource sharing between nominal and checking data paths. The algorithm grants that the required checking periodicity is satisfied while minimizing additional costs in terms of functional units. Risk of error aliasing due to resource sharing is analyzed.
