cable connections and "part" command specification The current
"part" database can be displayed by typing "part" followed by a
carriage return.
You must specify a particular instance upon which to operated.
Respecify the command with that information. That is, specify "erase
instanceName" and not "erase".
The specified device instance could not be erased. Check if data
protect is enabled as this disables the erase functionality. Also
check for the integrity of the cable connections.
When running functional test using the INTEST instruction, the
applied functional vectors mismatched the predicted values. This
can be either a functional error in the design or an error in the vectors
specified. This will also occur when vectors targetted for a different
design are applied. Re-check the integrity of your design database
information.
The specified device instance could not be verified. Check if data
security is enabled as this disables the readback functionality. If
this is not the case, check for the integrity of the cable connections.
If error persists you may have a bad part and Xilinx customer service
should be contacted.
