Warning (10034): Output port "cascade_out" at altera_pll.v(276) has no driver - Warning (10034): Output port "cascade_out" at altera_pll.v(276) has no driver Description You may see this warning in the Quartus® II software version 12.1 for designs that use the Altera_PLL megafunction. The cascade_out port is used when cascading one fPLL to another adjacent fPLL. If you do not enable this port in the Altera_PLL megafunction in your design, the warning may still be generated during compilation. Resolution You can safely ignore this warning. It is generated by mistake.
