Developing Globally-Asynchronous Locally- Synchronous Systems through the IOPT-Flow Framework
| Resumo: | Throughout the years, synchronous circuits have increased in size and com-plexity, consequently, distributing a global clock signal has become a laborious task. Globally-Asynchronous Locally-Synchronous (GALS) systems emerge as a possible solution; however, these new systems require new tools. The DS-Pnet language formalism and the IOPT-Flow framework aim to support and accelerate the development of cyber-physical systems. To do so it offers a tool chain that comprises a graphical editor, a simulator and code gener-ation tools capable of generating C, JavaScript and VHDL code. However, DS-Pnets and IOPT-Flow are not yet tuned to handle GALS systems, allowing for partial specification, but not a complete one. This dissertation proposes extensions to the DS-Pnet language and the IOPT-Flow framework in order to allow development of GALS systems. Addi-tionally, some asynchronous components were created, these form interfaces that allow synchronous blocks within a GALS system to communicate with each other. |
