7.1isp3 PAR, Virtex-4 RocketIO - Unroutable design error occurs when GT11CLK drives DCM

描述

7.1sp3 PAR fails to route when GT11CLK or GT11CLK_MGT drives DCM. The following message occurs in PAR: 

 

"IMPORTANT MSG: UNROUTABLE DESIGN; CHANGE PLACEMENT or EASE CONSTRAINTS"

解决方案

When PAR instantiates the macro for DCM and DCM is connected to GT11CLK, PAR fails to route. 

This issue has been fixed in 7.1i Service Pack 3.
