Hi
I have done a DDR2 signal integrity-batch simulation using hyper lynx 8.2.1
I got the attached excel sheet after the simulation.
On what basis the following parameters are measured and compared? Are there any standard values to compare? Please explain.
Rise Min Delay [ns]
Rise Max Delay [ns]
Rise Ref Time-to-Vmeas [ns]
Fall Min Delay [ns]
Fall Max Delay [ns]
Fall Ref Time-to-Vmeas [ns]
Flight Time Comp. [Yes/No]
Rise Rail Overshoot [mV]
Rise Dynamic Rail Overshoot Time [ps]
Rise SI Overshoot [mV]
Fall Rail Overshoot [mV]
Fall Dynamic Rail Overshoot Time [ps]
Fall SI Overshoot [mV]
Ringback Delay [ps]
Rise Closest Ringback [mV]
Fall Closest Ringback [mV]
Rise/Fall Multi Cross [Pass/Fail]
Rise/Fall Delay Error [Pass/Fail]
