Solution

New Feature 

- ISE 10.1 design tools support</b 

- FCB Delay Compensation 

- Enhanced Client Data Interface 

 

Resolved Issues  

- FCB serial output bit order 

- Version fixed: v1.1 patch 1 

- CR 446560: The FCB serial output is generating MSB first which is incorrect. The bit order is now LSBit first.  

 

- Setting Delta negative in core does not work for long frames. 

- Version fixed: v1.1 patch 2 

- CR 447753: The delay adjust logic is corrected in this version 

 

- Width mismatch in dlink_rx_sync_fsm_if.vhd 

- Version fixed: v1.1 patch 2 

- CR 447764: Width mismatch in dlink_rx_sync_fsm_if.vhd causes a synthesis warning in XST. 

 

- FCB accuracy improvement 

- Version fixed: v1.1 patch 2 

- CR 447765: FCB counter stops half a cycle too early. This causes a small error in the timing of the FCB re-generation. The sample point has been changed to the middle of the FCB bit to improve accuracy.  

 

- Incorrect procedure in Tx Sync  

- Version fixed: v1.1 patch 3 

- CR 448951: Incorrect procedure in Tx Sync for PMA setphase. The patch implements the updated procedure.  

 

- The transmit PLL dividers in the GTP cannot be used  

- Version fixed: v1.1 patch 3 

- CR 448950: The transmit PLL dividers in the GTP cannot be used when the transmit buffer is bypassed. The patch fixes this by using the common PLL divider in the GTP tile.  

 

- Auto-negotiation Reliability  

- Version fixed: v1.1 patch 3 

- CR 450497: Auto-negotiation unreliable. The patch improves the reliability of the auto-negotiation procedure.  

 

- The DCM PLL lock cannot be relied upon  

- Version fixed: v1.1 patch 3 

- CR 452512: The DCM PLL lock cannot be relied upon for 100 microseconds following a reset. The patch adds logic to delay the sampling of the lock signal.  

 

Known Issues in v1.2 

There are no known issues for OBSAI v1.2 core at this time.
