I have to implement FIR filters with constant coefficients. I am using the FIR compiler 7.2. Because coefficients are constants I would like to avoid the using of DSP blocks. In synthesis parameters, I force the maximum number of DSP equal to 0.
However, after the implementation, the resources utilization report told me that DSP BLOCKS have been used.
Is it possible to force the ip core generator to not use DSP-blocks?

I am not sure for the IP core, but generally we can \restrict absorption of Registers into DSP blocks using the KEEP attribute.
For more information please check page no.60 of thr following UG901 link:

If the DSP blocks are coming from IP in instantiated form then it cannot be avoided.
