WebMar 22, 2006 · Re: Retiming. - Retiming is NOT a technique used in the STA but in Synthesis. - Retiming (Register retiming) is a sequential optimization technique that moves registers through the combinational logic gates of a design to optimize timing and area. - For synopsys DC tool, there are 3 kind of retiming method. WebAug 14, 2008 · A low-noise flip-flop clocked by the clean VCO signal can be used as a retiming stage to eliminate jitter when an FPGA is used to frequency-divide the VCO. The FPGA can be used to implement a narrow-band PLL for an external VCXO, with an external loop filter, and a loop-filter driver protected from reflected ground bounce from the FPGA.
