If you place the cell in the slices with pre-defined global signals, No, it is not required since they will be connected automatically, otherwise you have to script the global signals' connection to the cells (FDCEs)

Dear @ads-ee,
I did not create a new post for this question since it is related to this post. As I look to the SLICE configuration, I see the flip-flops AFF, A5FF, DFF, and D5FF are of type of "CELL" and the BFF, B5FF, CFF, and C5FF are of type "BEL". BELs or logic elements are related to LUTs. I am wondering if there is a command to create and place LUTs using Tcl script as we do for flip-flops (FDCEs). I have looked at UG835 and I did not find any command related to LUT creation and placement ! Do you have any idea?
Thanks and Regards,
