EDISYN: A Language-Based Editor for High-level Synthesis

We describe a language-based editor, EDISYN, for developing behavioral programs for high-level synthesis. The aim of this editor is to provide a highly interactive environment at the front end of the synthesis task. EDISYN is customized for HardwarePal, a hardware description language, and is built with the Synthesizer Generator, a system for constructing language-based editors. EDISYN uses knowledge of HardwarePal to provide structural editing and immediate syntax and semantic error reporting while a HardwarePal program is being developed. In addition, EDISYN is combined with an incremental compiler which updates code in response to each modification to the program. The code can be further processed to realize a controller and a datapath.
