Stratix5 PLL (Megawizard Query)

[vlsi_freak]

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.


Generated file is shown below;

Code:

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.
