CAPACITANCE

At DDR2 data rates, it is recommended to simulate the performance of the module to achieve optimum values.

When inductance and delay parameters associated with trace lengths are used in simulations, they are

significantly more accurate and realistic than a gross estimation of module capacitance. Simulations can then

render a considerably more accurate result. JEDEC modules are now designed by using simulations to close

timing budgets.
