A Language and Toolset for the Synthesis and Efficient Simulation of Clock-Cycle-True Signal-Processing Algorithms

Abstract—Optimal simulation speed and synthesizability are contradictory requirements for a hardware description language. This paper presents a language and toolset that enables both synthesis and fast simulation of fixedpoint signal processing algorithms at the register-transfer level using a single system description. This is achieved by separate code generators for different purposes. Codegenerators have been developed for fast simulation (using ANSI-C) and for synthesis (using VHDL). The simulation performance of the proposed approach has been compared with other known methods and turns out to be comparable in speed to the fastest among them. Keywords—hardware description languages, simulation, synthesis
