Clocked Video Out VIP Timing analysis

Hello All,

I have been struggling for a few days now to solve my Timing analysis problems on my cyclone III design , but have had no luck at all.

I have simple design with a micron 8 mb sram controller, altera Test Generator, and Video , Altera Standard frame buffer ,Clocked out IP.

I have added, the VIP Video clocked out SDC Timing file to my time quest analyzer , as well as pll and sram contraints.

When Running Time quest and reading in the VIP Video clocked out SDC Timing file, I noticed that all the constraints in the Standard Altera VIP Video clocked out SDC Timing file(located altera\ip\clocked_out\lib),were ignored.

Further more when analyzing the system I notice that my design fails on Recovery paths on my PLL. After creating a report I have been able to figure out where the fail paths occur, but I have no idea how I can fix them.

I am attaching my project to this post, hope some one can help me.
