  • Patent number: 9747252
    Abstract: The present invention classifies all critical paths into two basic types: a series critical path and a feedback critical path, and divides each of wave-pipelined circuits into two components: a static logic part, called critical path component (CPC), and a dynamic logic part, formalized into four wave-pipelining components (WPC) shared by all wave-pipelined circuits. Each wave-pipelining ready code in HDL comprises two components: a WPC instantiation and a CPC instantiation wire-connected and linked by a new link statement. Each WPC has new wave constants which play the same role as generic constants do, but whose initial values are determined and assigned by a synthesizer after code analysis, so designers can use after-synthesization information in their code before synthesization for wave-pipelining technology.
