Aurora 8B10B v10.2 GUI - Validation failed for parameter C_GT_CLOCK1 error in second tab

Description

This issue arises when the target device is either an XC7VH580TFLG or XC7VH870TFLG device.

This answer record provides a work-around for generating an Aurora 8B10B core for these devices.

Solution

  1. Generate the Aurora 8B10B core for an XC7VH580THCG (instead of XC7VH580TFLG) or an XC7VH870THCG (instead of XC7VH870TFLG) device.

  2. Copy the IP to the corresponding FLG (XC7VH580TFLG and XC7VH870TFLG) package device.

  3. Update the below XDC constraint file for GT reference clock locations.
