6 years ago Can you provide some clarification on this? Are you saying that the netlist has a RAMB36E1 cell but when you query you cannot find any RAMB36E1 BEL’s to place it on (and that all you can find are RAMBFIFO36E1 BELs)? Or is it that you find the BEL but no pin mappings exist?
This might have to do with alternate site types. Or, it might have to do with dynamic pin mappings. Or, maybe both :-(
If you can help clarify things a bit I will do some digging tomorrow and get back with you (I have worked on both topics a lot in the past so should be able to help).

As such, the cell does not get placed and the script fails to make the pin mappings.
