AR# 11164
LogiCORE 1024-pt FFT v1.0 - Documentation (data sheet) incorrectly specifies WEA_X as used for DMS.
Description
Keywords: virtex, fft, 1024, WEA, WEA_X, WEA_Y
In the Virtex 1024 point FFT core datasheet, on page 5, the WEA, WEA_X and WEA_Y signals are defined. It says that WEA is only used in Single Memory Space (SMS) configuration, and WEA_X and _Y are used in both DMS and TMS. On page 12, in the DMS diagram, WEA is used, not WEA_X.
Solution
WEA are used for SMS and DMS. WEA_X and WEA_Y are used for TMS only.
