roughly readding this: <div class='quotetop'>QUOTE </div> --- Quote Start --- Error: Symbolic name "extclkena3" must be port of megafunction, macrofunction, primitive, or state machine "pll"[/b] --- Quote End --- I suspect the PLL outputl extclkena3 is somehow misaligned with you destination port. You can check them in RTL viewer. Wait for more detail.
