Abstract
In this paper, we propose a design and implementation method for priority queuing mechanisms on FPGAs. First, we describe behavior of WFQ (weighted fair queuing) with several parameters in a model called concurrent periodic EFSMs. Then, we derive a parameter condition for the concurrent EFSMs to execute their transitions without deadlocks in the specified time period repeatedly under the specified temporal constraints, using parametric model checking technique. From the derived parameter condition, we can decide adequate parameter values satisfying the condition, considering total costs of components. Based on the proposed method, high-reliable and high-performance WFQ circuits for gigabit networks can be synthesized on FPGAs.
