Re: Stratix5 PLL

Altera_Forum · ‎12-14-2011

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.

Do you see the qip file in the design files.?

there should be a pointer to the sub files in the mega-function directory that will include the pll_test_0002 file
