GTX transceiver settings have been updated to work around the Virtex-6 GTX Transceiver Delay Aligner Errata.
GTX Wrapper updated
The GTX Wrapper updated per latest recommendations for GTX Transceiver for PCI Express.
Default Reference Clock Frequency updated
The default reference clock frequency for Designs with Link Speed 5.0 Gb/s been changed from 250 MHz t100 MHz.
PMA_RX_CFG attribute in GTX wrapper updated
The PMA_RX_CFG attribute in the GTX wrapper has been updated to be set based on Synchronous or Asynchronous clocking selected (Slot Clock selection).
Transaction Buffer Pipeline default setting for 8 lane Gen2 configuration
The default setting for Transaction Buffer Pipeline for 8 lane Gen2 configurations has been updated to "Buffer Write and Read"
INTERRUPT_PIN attribute update based on Legacy Interrupt option in the GUI
Issue resolved where unchecking the Legacy Interrupt option was not updating the INTERRUPT_PIN attribute.
trn_trem_n not connected in PIO_EP.vhd
Issue resolved where trn_trem_n was not connected ttrn_trem_n_int, in PIO_EP.vhd, causing this output to not be driven.
Note: CR 579207 is listed as resolved in the text readme that accompanies the core. This is a documentation mistake as this CR was not actually implemented since the GTX Delay Aligner work-around does not allow this use model.
