Known and Resolved Issues
The following table provides known issues for the LogiCORE IP Discrete Fourier Transform (DFT) core, starting with v4.0, initially released in Vivado 2013.1.
Note: The "Version Found" column lists the version the problem was first discovered. The problem might also exist in earlier versions, but no specific testing has been performed to verify earlier versions.
|Answer Record||Title||Version Found||Version Resolved:|
|(Xilinx Answer 70698)||Discrete Fourier Transform (DFT) v4.0 - Some configurations of the DFT IP core might be logically incorrect following synthesis when Vivado 2018.1 is used and synchronous reset is not present. |
This will manifest as mismatches versus behavioral simulation on all core outputs.
|(Xilinx Answer 57570)||Discrete Fourier Transform (DFT) v4.0 (Rev. 2) - When behavioral simulation is run on the DFT v4.0 IP core with Cadence IES in 2013.3, some outputs do not agree with the C model output||v4.0(Rev.2)||v4.0(Rev.2)|
