has no load. PAR will not attempt to route this signal."">
When implementing SPI-4.2 design, I receive several warning messages from PAR and Bitgen. These only occur when the options "Static Alignment" and "Invert SPI-4.2 with XOR Mask" are used.
Examples of the warning messages are listed below:
PAR Warning:WARNING:Par:288 - The signal pl4_v10_1_pl4_snk_top0/U0/io0/StaticAlign.buffer_data/stat_v6.BUFIN00.Dat00/OB has no load. PAR will not attempt to route this signal.
Bitgen Warning:WARNING:PhysDesignRules:367 - The signal <pl4_v10_1_pl4_snk_top0/U0/io0/StaticAlign.buffer_data/stat_v6.BUFIN00.Dat00/OB> is incomplete. The signal does not drive any load pins in the design.
