Virtex-7, Vivado SIOD - GTH 2.01 fails timing using the example design

Description

If using a Vivado Serial I/O Debug (SIOD) 2.01 core for a GTH on a Virtex 7 X980T 1926-2L, timing errors are seen in the example design when the following settings are selected:

  • 1 quad (quad 217), running at 11.2 Gb/s, 32-bit data, using the quad PLL
  • QUAD 217 REFCLK1 at 175 MHz
  • Channel 0 TXUSRCLK source
  • No external system clock

Solution

This is a known issue and will be fixed in a future revision of the tools.
