Kintex-7 GTX IBERT - what does the silicon version drop down menu mean?

Description

In the Kintex-7 GTX IBERT wizard, there is a drop down menu called "Silicon Version" on the first page. What does this mean?

Solution

When using the Kintex-7 GTX IBERT core with engineering sample silicon, it is important that the proper selection for this drop down menu be used in order to generate a working design for the part. There are multiple versions of engineering sample parts available and IBERT needs to target the correct silicon version in order to generate a working design.

To determine what version of silicon is in the device, please see (Xilinx Answer 37579); refer to the JTAG IDCODE section of the answer record. This section instructs how to read back the JTAG IDCODE for the device. The sections below will instruct which option for the "Silicon Version" drop down should be used based on the value for JTAG IDCODE.

Generating Kintex-7 GTX IBERT core in version 13.2 and 13.3:

  • Select "1.0" if JTAG IDCODE = 0
  • Select "1.1" if JTAG IDCODE is 1 or greater

Generating Kintex-7 GTX IBERT Core in version 13.4:

  • Select "Initial ES" if JTAG IDCODE is less than 3
  • Select "General ES" if JTAG IDCODE is 3
