The proposed RTL morphing enables true IP-reuse design through flexible control of the RTL structure under the changes in performance requirements or delay constraints. This flexible RTL restructuring is provided by a new path-depth controlling method, which can optimize the depth of any path by changing the if-then-else nesting order of a basic logic unit (called a decision unit). The use of RTL morphing reduces the design period of a time-to-market pressured SoC of 4M transistors by two months with 18% operating frequency improvement
