I'm working on XAPP495 on Digilent Atlys board with ISE 14.7 I want to run and test "vct_demo" coming with the XAP 495. I tried to compile it (with ISE 14.7) and failed because of the following errors:
ERROR:PhysDesignRules:2502 - Issue with pin connections and/or configuration on block::. BUFIO2 has an invalid setting of DIVIDE by 2. This setting is not supported. For more information please see Answer Record 56113.
ERROR:Pack:1642 - Errors in physical DRC.
I simply imported all the *.v files as well as the corresponding *.ucf
Can this here be a simple version issue? - Is it a matter of error level which is stricter than in former versions?
Any help is appreciated.
