The User Guide utilization section shows that the TRD uses 60 RAMB36E1 components, but I see 96 used in my map report. Why is there such a big difference?
The User Guide number of 60 for RAMB36E1 components includes 32 used as a Simple Dual Port (SDP) RAM in "READ_FIRST" mode. This was changed to use twice as many RAMB36E1s using True Dual Port in "WRITE FIRST" mode. Therefore, 32 more RAMB36E1s were added to implement this change.
