Virtex-5 RocketIO GTP - Designs show timing failures on CHBONDO / CHBONDI ports in ISE 9.2.01


In ISE 9.2.01, designs that previously passed timing could fail timing on the CHBONDO / CHBONDI ports of the GTP.


The timing analysis tools in ISE 9.2.01 contain unrealistically conservative timing requirements that are not accurate to silicon. The speed files for GTP are fixed in ISE 9.2.02. Designs using the GTP's channel bonding functionality should be run in ISE 9.2.02 and later.
