设计者在UCF文件中通过SYSTEM_JITTER关键字指定的系统抖动参数是直接传递至XST静态时序分析工具的。 XST静态时序分析工具使用SYSTEM_JITTER约束时会根据被分析路径中同步元件的数量,按照“和方根”的方式对本路径的系统抖动进行合成,这一点在UG612中并无说明。 一个添加了200ps SYSTEM_JITTER约束的设计,查看布局/布线完成...
I was running a new pc based on z490 board and 10900k, for audio playing, which is require system in low latency mode. running centos 7.6 and everything tuned in low latency mode(i.e. no c stat and max performance in bios, ht disabled), I running sysjitter app to check m...
24518 - 14.x/2012.x Timing/Constraints - How can the SYSTEM_JITTER constraint be used? Description How can a value for the SYSTEM_JITTER constraint be generated? Solution The SYSTEM_JITTER constraint is used to represent the power noise, board noise, and any extra jitter of the overall syst...
20828 - 13.1 Constraints - How can I set the jitter for CLK0 and CLKFX separately (uncertainty)? (INPUT_JITTER/SYSTEM_JITTER) Description When I use CLKFX to drive a system, the clock uncertainty (as used by the Timing Analyzer) is zero if the input clock jitter is set to zero. Conv...
The system processes the second set of presentation time stamps of the transcoded video stream to determine if the second presentation time stamps include jitter, and based upon determining the second set of presentation time stamps include jitter modifying the second set of presentation time stamps ...

Techniques for emulating operating system jitter on a platform using a given trace are provided. The techniques include calculating a scale factor, wherein the scale factor is equal to a maximum of measured overhead of introducing synthetic jitter on the platform and a resolution of one or more...
A jitter measurement circuit includes an addition circuit to add a digital rectangular signal to an adjustment signal generated by a circuit that generates a first error signal based on a phase difference between a first clock signal or a data signal on which the first clock signal is superimpose...
