Description

FIR filters with large numbers of coefficients and with Force Non-Symmetric Structure turned on, cannot generate a netlist successfully.

FIR filters with large numbers of coefficients and with Force Non-Symmetric Structure turned on.

The Quartus II software cannot generate a netlist or an IP functional simulation model.

Resolution

For FIR filters with Force Non-Symmetric Structure turned on, restrict the set of coefficients to 1500 or fewer.
