Electronic – PCB footprint of Xilinx Kintex 7 FPGA


I am laying out a board with a Xilinx Kintex 7 FPGA (serial number XC7K70TFBG676). The first step is to create a footprint of the FPGA for my layout tool, the Cadence Allegro PCB Editor.

Does Xilinx provide Allegro footprints of their FPGAs for easy import?

It is not even necessary for you to ask xilinx, since someone else has done so already. A quick google search ("xilinx kintex footprint") gives me this as the third result, where a Xilinx employee states that the

Kintex-7 FF676 is the same as every other Jedec 1.0mm 27x27 device, so the PCB decal footprint is the same.

Which indicates that the footprint of that specific kintex is standard. The only difference between the FFG and the FBG is the thermal characteristic and the height of the package, so the statement above should apply to the FBG also.

Since the part is standard, some tools have a part creation feature where it is possible to specify the package type and pitch and other dimensions and the tool will create the part for you.
