Scaling is needed to prevent overflow. Scaling schedule tells the engine to scale the output after certain stages. Please read page 25 and 57 of this document for the detailed explanation https://www.xilinx.com/support/documentation/ip_documentation/xfft/v9_1/pg109-xfft.pdf

Hello @kapildev 

 

As @baltintop   mentioned, Table 4-3 described the scaling in details.
