Error (129029): Input port CLK on atom "<DLL instance>", which is a arriav_dll primitive, is not connected to a valid source File: <project path>/dll.v Line: 53

Description

The PLL output cannot be connected to the DLL directly when Enable access to dynamic phase shift ports is selected in the Altera PLL MegaWizard™ GUI. The Quartus® II software tries to insert the pll_dll_output atom between the PLL and DLL and causes the above fitter error.

Workaround/Fix

To work around this issue, insert the pll_dll_output atom as shown below:

arriav_pll_dll_output arriav_pll_dll_output_test(
.cclk(from_pll_outclk_0),
.clkin(1\'b0),
.clkout(to_dll_clk0)
);
