摘要
A physical synthesis system includes a path straightening module, an ideal critical point identification (ID) module, and a free-space ID module. The path straightening module identifies at least one meandering critical path of a circuit, and generates a reference curve based on dimensions of the critical path. The ideal critical point ID module identifies at least one critical point on the reference curve. The free-space ID module identifies at least one free-space to receive a gate with respect to at least one critical point. The physical synthesis system further includes a free-space selector module and a gate modification module. The free-space selector module determines a modified slack timing value based on relocating the gate to the at least one free-space. The gate modification module moves the gate to the at least one free-space when the modified slack timing value is greater than an initial slack timing value.
