Dear All, I am using abEyeCross.il from solution 11395772(https://support.cadence.com/apex/ArticleAttachmentPortal?id=a1Od0000000nX0ZEAU&pageName=ArticleContent ). This is to find peak-to-peak Deterministic jitter (DJ) when I give a supply sinusoidal noise ( of 20 mV amplitude and 11.11 MHz frequency). I am giving a PRBS pattern of UI=31.25 pS as the input data stream. I am now finding the DJ in the output data stream. I am trying to verify that whether abEyeCross.il is giving correct result when I compare manually the Deterministic jitter from the actual Eye-Diagram. But, Looks like I am getting wrong result from abEyeCross.il. Can anybody please tell why it is giving wrong results. I am also posting the both way results below. abEyeCross.il Results:- I use the commands in CIW as below:- jit=abEyeCross(vtime('tran "/rxleq_lpbk") 0n 105n 31.25p 0 "rising") srrWave:0x33bed0a0 DJ=peakToPeak(jit) DJ=3.123789e-11 =31 pS I got DJ = 31 pS Below shows the DJ value I got from Eye-Diagram:-
