QSYS FFT 16.0 issue

Altera_Forum · ‎10-18-2016

Hi,

I’m trying to generate FFT 16.0 Core with QSYS. With the setting shown in the attached file the generated code can be synthesized. If I change Data Input Width and Twiddle Width to 32 Bit the .hex files will be generated wrong.

fft_core_fft_ii_0_1n64sin.hex

:03000000000000fd

:030001000c8bd35c36

:0300020018f8b83cf7

As you can see fft_core_fft_ii_0_1n64sin.hex the length of the first doesn't match to the length of other lines.

Output from Quartus: Error (113029): Data size does not match the number of bytes at line 2 in Hexadecimal (Intel-Format) File "fft_core_fft_ii_0_1n64sin.hex"

How to fix this problem?

Best regards

Samuel

The problem is still open. I attached the qsys files, the bug should easily be reproduced.

Thank you for your help
