How to determine the SI parameters?

archive
archive over 19 years ago

Hi all,
I am a freshman in SI field. Now I am simulating the signals between an ARM9 processor and 133M SDRAMs. Now, the biggest problem I have to solve is to determine the overshoot limitation. I list the values in the ABSOLUTE MAXIMUM RATINGS section of the SDRAM's and processor's datasheet in the following table. 

Parameter                                       Value
SDRAM    Voltage on any pin relative to Vss     -1.0 - 4.6 V
Processor   DC I/O voltage                                   -0.5-4.8V
 
Can I use –0.5 - 4.6V as the overshoot falling/rising parameters?
 
Thanks.
