I have created a decimation filter using MegaCore FIR Compiler II, this produces the frequency plot I want and compiles without errors.
When I add this to my design in Quartus and compile I get the following error messages:- 15008 MLAB "dsp_block:inst 27| ................. |altsyncram_atv3:auto_generated|lutrama0" on port "Port A, data In" has illegal width "0". The correct width is "1" 15010 MLAB "dsp_block:inst 27| ................. |altsyncram_atv3:auto_generated|lutrama0" is implementing memory in non-ROM mode, but the port "Port A, Data In" is not connected 15464 WYSIWYG primitive "dsp_block:inst 27| ................. |altsyncram_atv3:auto_generated|lutrama0" has mismatched parameters for port Port A, Data In Any help on how to fix this would be much appreciated Using Quartus V14.0 Device Cyclone V 5CSEBA6U23I7 filter.vhd -- Generated by Altera MegaWizard Launcher Utility version 1.0 -- ************************************************************ -- THIS IS A WIZARD-GENERATED FILE.
