Hi all - I'm a new member of SI mailing list and would like to pose a
question. I'm wondering if there is a way to add jitter or a variable amount of
uncertainty to the rising/falling edges of a signal source such as 'pulse' or
in my case the built-in PBRS function (lfsr). I'm attempting to characterize a
valid data window for a DDR2 memory interface, and would like to introduce more
uncertainty into my source than is currently being generated by the output
buffer of my SDRAM model.
Regards,
