How can place and route results be improved without adding timing constraints? |
|||||||||
|
To improve runtime for timing driven implementation, the place and route defaults have changed to NOT run Cost Based and Delay Based Clean-up passes. Because of this change, you may notice lower design performance results from PAR. This will occur on designs that are run in v2.1i with no timing constraints applied (non-timing driven). To get a more "realistic" estimate of how your design will perform without any timing constraints applied, please follow this recommendation:
