Dealing with Clock Jitter in DDR2 and DDR3 Designs

For the past couple of days i have been part of a design that interfaces a DDR/DDR2 memory. But lately after a recent pll model integration the whole scenario changed and i was in the middle of a clock jitter related timing check failure. This led me to do some Google search when i found this interesting 3 part article based on the same title.
