INFO:Xst:2371 - HDL ADVISOR - Logic functions respectively driving the data and gate enable inputs of this latch share common terms. This situation will potentially lead to setup/hold violations and, as a result, to simulation problems. This situation may come from an incomplete case statement (all selector values are not covered). You should carefully review if it was in your intentions to describe such a latch.

(*) These 8 clock signal(s) are generated by combinatorial logic,
|
|
and XST is not able to identify which are the primary clock signals.
|
|
Please use the CLOCK_SIGNAL constraint to specify the clock signal(s) generated by combinatorial logic.
|
|
INFO:Xst:2169 - HDL ADVISOR - Some clock signals were not automatically buffered by XST with BUFG/BUFR resources. Please use the buffer_type constraint in order to insert these buffers to the clock signals to help prevent skew problems.
