AM335x Power Estimation Tool - Simulated Capacitance Question

Clinton Rodgers
Genius 13235 points

Hi,

We are using the AM335x Power Estimation Tool (PET - http://processors.wiki.ti.com/index.php/AM335x_Power_Estimation_Tool) and would like to know how some of the capacitance was simulated. I have looked through the wiki, but did not see these specifics there. The questions we have are listed below:

1. Can you elaborate on how much capacitance was simulated on the high speed switching lines for the 'active power' calculations?

2. Were these values based on just the worst case values of the 335x package, or instead was a transmission line and/or load capacitance assumed?

Thanks,

Clinton
