LogiCORE xFFT v3.1 Patch - I cannot reach the speeds listed in the Data Sheet for Virtex-4

描述


General Description: 
I cannot reach the speeds listed in the Data Sheet for Virtex-4. Why?

解决方案


The numbers in the Data Sheet are incorrect. These numbers were run on unrouted designs, and did not include net delays. A new version of the core is being developed that will be faster. 
 
Please see (Xilinx Answer 21453).
