HDL code restructuring using timed decision tables

Abstract

Behavioral HDL descriptions from designers are structured in a program calling hierarchy for the purposes of programming convenience and conceptualization. This code structure is often not suitable for direct synthesis into digital hardware. For instance, information regarding operation exclusivity and resource sharing can be explored by restructuring the code. In this paper, we present a method to restructure behavioral HDL code using merging and decomposition of Timed Decision Tables (TDTs).
