of ARESETN. The workaround is to ensure no transfers are
attempted for 2 clock cycles following the release of ARESETN.
- CR 591111.
2. The bit-accurate C model and Matlab MEX function for the FFT core
can return incorrect results when configured to perform a Block
Floating-Point FFT using the Pipelined, Streaming I/O architecture.
- CR 639407
- AR 53087
5.2 Vivado
1. Core may fail to compile in XSIM.
- CR667416
