Resumo(s)
The main goal is to develop a solution for the interconnection of components constituent of a GALS - Globally Asynchronous, Locally Synchronous – system. The components are implemented in parallel obtained as a result of the partition of a model expressed a Petri net (PN), performed using the PNs editor SNOOPY-IOPT in conjunction with the Split tool and the tools to automatically generate the VHDL code from the representations of the PNML models resulting from the partition (these tools were developed under the project FORDESIGN and are available at http://www.uninova.pt/FORDESIGN). Typical solutions will be analyzed to ensure proper communication between components of the GALS system, as well as characterized and developed an appropriate solution for the interconnection of the components associated with the PN sub-models. The final goal (not attained with this thesis) would be to acquire a tool that allows generation of code for the interconnection solution from the associated components, considering a specific application. The solution proposed for componentes interconnection was coded in VHDL and the implementation platforms used for testing include the Xilinx FPGA Spartan-3 and Virtex-II.
