See Mentor’s AppNote 10685 (“Explanation of the HyperLynx DDR Wizard Results Spreadsheets”).
indeed much of my doubts are cleared but while read measurements what is the significance of Stimulus Offset
and it is shown in negative still the signal in referenced manual is passed . Plz throw some light on this stimulus offset.
As for write caese the set up & Hold time margin should be positive for Pass,
Does the same thing applies for read Pass or fail ?
If the signal fails what step we can take for rectifying this problem so that signal can Pass?
Hi Cristian ,
In spreadsheet the set up margin & Hold margin is given for one signal at a time .
But if i want to measure average set up margin and average hold margin for a group of
signal w.r.t strobe like Data bytelane"0 " (DQ0-7) w.r.t. DQS0 & All ADDRSS/COMMAND
w.r.t. Clock then how can i do that.
