Virtex-5 GTX RocketIO SIS Kit - GTX REFCLK power supply labeled MGTAVCCPLL, should be MGTAVTTX


A number of the Virtex-5 SIS Kit design files have the GTX REFCLK power supply labeled as MGTAVCCPLL. It should be MGTAVTTX.

The affected files are:

  1. v5_gtx_refclk_fast.sp
  2. v5_gtx_refclk_slow.sp
  3. v5_gtx_refclk_typ.sp
  4. demo_testbench_v5_gtx_refclk.sp


The naming discrepancy should not affect the results of the simulation. The value that is used is correct, but note that MGTAVCCPLL in the SPICE deck for the GTX REFCLK is referring to MGTAVTTX.

The functionality of the models is not affected and this inconsistency between the User Guide and the design files will be addressed in a later release of the design files.
