LogiCORE IP Display Port v1.2 - The example design does not meet timing when I target a Spartan-6 device. Why?

Description

The example design does not meet timing when I target a Spartan-6 device. Why?

Solution

The timing for the Spartan-6 device is very tight and requires the use of area constraints in order to meet timing. 

There are some constraints in the example design UCF to help meet timing, but in some cases, the user might need to modify the area constraints to meet timing. 

You can modify the constraints using the PlanAhead tool, or by editing the UCF file in a text editor. 

You might also want to try to change the map options (-register_duplication, -logic_opt, -retiming), or to apply an area group.
