Presentation Title: It’s all in the Model: Verifying Complex Arbitration Schemes using Formal
Abstract: The design of multi-transactional systems is a key to optimize performance where several masters arbitrate over a shared resource. The arbitration schemes are carefully designed to avoid hazards, race conditions, starvation and deadlocks. Arbitration verification is a challenge when policies are complex and the number of requestors is large. We present an abstract formal model within 80 lines of modelling code that uses a single assertion to exhaustively verify a range of arbiters within Imagination. We provide a reusable model that provides one of the highest levels of assurance and proves correctness in seconds for some arbiters with 256 requestors.
