Patch SPR#: 311266
SPRs fixed: 307178, 309110
//**************************************************************** 

Problem:  Stratix IV GX/GT receivers require tweaking on power-up due
	  for best operation and highest bitrate and signal integrity
	  performance. This requires a specific algorithm implemented
	  in soft-logic to perform the tweaks, which to-date had not
	  yet been proven.
 

Solution: This patch includes the performance tweaking soft-logic
	  block that will find the properly configured receivers, and
	  automatically perform the tuning.

 
Caution - You must either have previously installed the Quartus II
          software version 9.0 or must install the Quartus II
          software version 9.0 before installing this patch.
          Otherwise, the patch will not be installed correctly and
          the Quartus II software will not run properly.
