I have some questions regarding the FF deployment in the PLU module:
"The outputs of up to four of the LUTs can be captured in one of the four state flip-flops" UM
Do this mean that it is only possible to use the FFs with LUT0, LUT1, LUT2 and LUT3 ? Since in the configuration tool there is a warning to use assign the FF to the LUT with the same index (also when mapping it only show FF with index from 0 to 4) .
"which can then be used as primary outputs and/or connected to the inputs of other LUTs." UM
Using the configuration tool (direct, LUT-based design), I was trying to use the output of one of the LUTs as input for a FF and in the same time as an input for and other LUT (also to one of the primary PLU outputs) but the was only possible to be done from one entity to just an other entity, not more than one in the same time (Yallow arrow in the figure below).
Thank you for your help.
