Improved VHDL Input for High-Level Synthesis Tool xTractor
Peeter Ellervee, Eero Ivask, Margus Kruus · Proceedings of the ... biennial Baltic Electronics Conference · 2006
In this paper, an improved version of VHDL compiler for an academic high-level synthesis tool xTractor is presented. A synthesizable subset of behavioral VHDL, accepted by the compiler, is described in brief. Improvements that allow descriptions at higher abstraction level are outlined. The compiler translates the behavioral VHDL subset into control oriented flow-chart like internul description IRSYD. The mapping of higher abstraction level VHDL constructs into IRSYD is described in more details. A short description of the synthesis tool is presented
