The following warning occurs during mapping in a Virtex-5. Is the timing driven map otion (-timing) not supported for Virtex-5?
"WARNING:Map:165 - The command line option -timing is not supported for this architecture, and will be ignored."
This warning message is misleading and will be modified in a future ISE revision. The timing driven packing flow is the normal (and only) packing flow for the Virtex-5 devices and, consequently, the -timing command line option is no longer necessary. The message is an indication that the -timing switch has no effect.
