Super ContributorWhat you can do is create a wrapper to wrap around this FFT2048 and with the top level name FFT2048_no_DSP and another name with FFT2048_with_DSP. After creating this two wrapper, you can create bdf out of it and use it to your bdf.
Since I had very long did not touch on bdf, i remember seeing customer use attribute in the bdf itself. But I can't remember how they have do it.
We dont really encourage user to use BDF anymore, we encourage user to use verilog and vhdl code. As it is really not that hard to used.
Occasional Contributorwhat ever i have messaged about the usage is like using that attribute in a wrapper kind of code only. But still you can see 0% dsps used.
