Stratix5 PLL

Hi,

I had generated Stratix5 PLL (s5_pll) using Megawizard Plugin and the created pll instance is pll_test_0002 with a top level wrapper arouND IT.

tHE GENERATED FILE IS SHOWN BELOW;

module pll_test (
		input  wire  refclk,   //  refclk.clk
		input  wire  rst,      //   reset.reset
		output wire  locked,   //  locked.export
		output wire  outclk_0, // outclk0.clk
		output wire  outclk_1  // outclk1.clk
	);
	pll_test_0002 pll_test_inst (
		.refclk   (refclk),   //  refclk.clk
		.rst      (rst),      //   reset.reset
		.locked   (locked),   //  locked.export
		.outclk_0 (outclk_0), // outclk0.clk
		.outclk_1 (outclk_1)  // outclk1.clk
	);
endmodule

Now i have a top level instance top.v with instance pll_test along with some sub-modules.

While synthesis in Quartus, toll gives below error;

--------------------------------------------------------------

Error (12006): Node instance "s5_pll_inst" instantiates undefined entity "s5_pll_0002"

Error: Quartus II 32-bit Analysis & Synthesis was unsuccessful. 1 error, 0 warnings

--------------------------------------------------------------

This error indicates, s5_pll_0002 (generated by Megawizard), Quartus tool is not able to identify.

Please guide me to get rid of this error.

Regards,
