Virtex-6 FPGA Connectivity Kit TRD - Block RAM Utilization

描述


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?

解决方案


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.
