Xilinx SYSTEM_JITTER, INPUT_JITTER Questions - Part II

Dec 15, 2006 0 Replies

How are these used in the case of FROM TO specs?



For example, CLK In goes to a DCM, the CLK0 and CLK180 are used as CLK and CLKN.



SYSTEM_JITTER = 100pS INPUT_JITTER = 200pS



timegroup 1 is on CLK0 timegroup 2 is on CLK180



if I have a FROM timegroup1 TO timegroup2 of 2400 pS, how will the timing analyzer figure in the two jitter specs and the DCM jitter/skew values?
