[SI-LIST] Re: What is the frequency range of the Stratix III core

Alexandre, Altera has a power planning tool that is part of Quartus.  
For impedance you will need to estimate the number of resources that you 
will be using and their switching frequency.  Alternatively, the 
estimator will evaluate a completed design.  To get the details of the 
component parasitics you need to talk to Altera.
