7 years agoRather than removing the unrolls, it is probably best just to decrease the unroll factors up to a point where the predicted DSP utilization by the compiler goes below 100%. When you overutilize the DSPs, the mapper will try to map the extra functions to logic, which will significantly increase the logic usage and complicate placement and routing and result in much longer placement and routing time.
