100 MHz Clock

deaxman

How can I access the 100 MHz PL clock? I can't find it in the UCF file.  I would like to know what LOC at least to connect it to.  Thanks!

    Do you mean one of the PL Fabric Clocks like FCLK_CLK0? It's part of processing_system7.
    In the System Assembly View  in Platform Studio, click the Ports tab, scroll down to processing_system7. Find the name of the clock that you want to use in the fabric. Click in the Connected Port column. All the connections for that port will appear in an editable form. Click the New Connection button to get a new connection, then select 'Make External'.
    NOTE: do not right-click in the Connected Port column. That usually deletes all the existing connections before adding any new ones.
