The examples (version 5.1) show 80 MHz on my machine -- but I can't guarantee they haven't been changed. > If I didn't talk with you, how would I know to change the sys clk to 80MHZ. You can check the settings in SOPC Builder. In the System Contents tab you can view all defined clocks and associated frequecies. Enable 'View->Show Clock Source' to identify the clock used for the component in question. You can double-click the pll component and open the MegaWizard for the details. You can also open the ptf file and view the clock_freq settings for the system module -- this is handy if you prefer the quick 'n dirty ;-) Regards, --Scott
