1. TerraSwarm Sponsored by the TerraSwarm Research Center, one of six centers administered by the STARnet phase of the Focus Center Research Program (FCRP) a Semiconductor Research Corporation program sponsored by MARCO and DARPA. Modelling And Analysis of IEEE 1588 (Precision Time Protocol) Ankush Desai, Sanjit Seshia, David Broman and John Eidson TerraSwarm Annual Meeting November 5 & 6, 2013 University Of California, Berkeley

2. Motivation Extending the state-of-the-art in verification of distributed protocols, with a special focus on protocols for time synchronization which is fundamental to TerraSwarm systems. IEEE 1588 is now getting adopted across domains, like industrial automation, telecommunication, etc. First to do Formal Analysis of IEEE 1588. TerraSwarm Research Center 2 11/05/2013

3. Modelling And Analysis of IEEE 15888 Heisenbugs due to asynchrony and concurrency are difficult to detect, diagnose, and fix! Model Based Design approach. Model the protocol using state machine based language for event driven program. Systematic testing of these models using Explicit state model checker. Efficient Bounding techniques.
