The customizable IBERT core for 7 series FPGA can be used for evaluating and monitoring the GTs.
The IBERT core can be defined and generated using the Vivado built-in IP Cores. And with the generated example designs the IBERT Test can be implemented.
|Ref Clock Selection||GT Clock(MHz)||Notes|
|TE0741||MGTREFCLK1 116||125||Both Quads can use same refclock|
Step to Step to generate the IBERT core:
- Create a new IP Location.
- Double-click IBERT 7 series GTP (or GTX).
- Define the new IBERT. Set the LineRate, select the DataWidth, the Quad count, the Refclk and the Clock Source.
- Generate the Core.
- Right-click the IP in the Sources view, choose "Open IP Example Design".
- A new project with the IBERT example design will be created and opened.
- Generate Bitstream. Open and view the completed design.
