This article deals with the formal validation of STIMAP, a medium access protocol that has been designed to meet the specific requirements of an implantable network-based neuroprosthesis. This article presents the modeling and the validation of its medium access, using model checking on Time Petri Nets. Doing so, we show that existent formal methods and(More)
Several solutions for implementing Petri net models on FPGA thanks to a transformation in a VHDL code have been proposed in literature. But none deals with the management of transition conflicts in the specific case of synchronous implementation of interpreted Petri nets. This article presents an automatic method to deal with conflicts from their detection(More)
This article deals with the temporal validation of STIMAP, a medium access protocol. This protocol has been designed to meet the specific requirements of an implantable network-based neuroprosthese. This article presents the modeling of STIMAP with Time Petri Nets (TPN), and the verification of the deterministic medium access it provides, using timed model(More)
A component-based approach to the specification and implementation of complex digital systems on field-programmable gate arrays (FPGAs) has been developed, with the behavior and composition of the components specified by Petri nets (PNs). Yet modeling behavior in the case of error becomes intricate if only PNs are used. In this case, the designer often has(More)
