System clock estimation based on clock wastage minimization


When synthesizing a hardware implementation from behavioral descriptions, an important decision is the selection of a clock cycle to schedule the datapath operations into control steps. Most existing behavioral synthesis systems either require the designer to specify the clock cycle explicitly or require that the delays of the operators used in the design be specified in multiples of a clock cycle. In the absence of any tool to guide the selection of a clock cycle, a bad choice of the clock period could adversely affect the performance of the synthesized design. We present an algorithm for estimating the system clock based on a clock wastage minimization criteria. Limitations of previous approaches to the problem are discussed. The results obtained prove that the clock cycle estimated by the Clock Wastage Minimization method produce faster designs than previous solutions to the problem.
