What is the location of IBUFDS_GTE2 in GT Transceiver of Kintex7?

Jump to solution

Hi,

I am examining a constraint file of an example design based on DMA Subsystem for PCIe IP core. In this constraint file, IBUFDS_GTE2 is defined as a reference clock. I start to search on it and relized that it i used for instantiation of sys_clk_p and sys_clk_n (PCIe reference clocks). My example design is written for Virtex7 and the location of is IBUFDS_GTE2 defined as X0Y3.  However I work with Kintex7 and couldnt find the location of IBUFDS_GTE2 in Kintex7. Does anyone knows something about it or have a document to share? Also if you have a constraint file for this IP core in Kintex7, can you share it with me?

Commmand line for Virtex 7 is : set_property LOC IBUFDS_GTE2_X0Y3 [get_cells refclk_ibuf]

Xilinx has a 7 series document for GTE2 but no detail is given for specific devices.

Name is same on Kintex7 devices based on the document.

I believe I have solved the problem. On the document at Appendix A, each connection is displayed for all 7 series devices. When I do the following:

set_property LOC IBUFDS_GTE2_X0Y0 [get_cells refclk_ibuf] 

it worked.
