Implementation

[yhwu]

In ML605 board, I try to implement a simple degin with GTX_X0Y17 and the reference clock is Q4_MGTREFCLK, 1 signals are not completely routed when i routed. I don't know why and how to solve this problem.

Here is the instance:

IBUFDS_GTXE1 q4_clk1_refclk_ibufds_i     (

         .O                              (gtx_rx_refclk_w),        

        .ODIV2                          (),        

       .CEB                            (1'b0),        

       .I                              (RX_REF_CLK_P),  // Connect to package pin F6( H6  is assiged)       

      .IB                             (RX_REF_CLK_N)  // Connect to package pin F5 (H5 is assigned)    

 );

error report:

1 signals are not completely routed.

Examine the partially routed design in FPGA Editor and examine the net. You can easily find  the unrouted net by setting the list window to "unrouted nets". If you can't figure out what's wrong post a screenshot of the highlighted net and a pin list.

I got it. It can't be routed because I use the reference clock to drive logics without BUFG. it can drive clock buffers. Thank you.
