8.1i NGDBuild -- Can the BEL constraint warnings from NGDBUILD (WARNING:NgdBuild:483) be safely ignored for XAPP509?

描述

Can the BEL constraint warnings from NGDBUILD (WARNING:NGDBuild:483) be safely ignored for XAPP509?

" WARNING:NgdBuild:483 - Attribute "BEL" on

"receiver_module/data_recovery_unit/lk.da/lf.7.Q_7" is on the wrong type of

object. Please see the Constraints Guide for more information on this

attribute."

解决方案

Yes, these warnings can be safely ignored. The constraints are placed on nets in the HDL code, but the synthesis tools push them back to the appropriate FFs that drive the nets during synthesis.
