Hello everyone. I'm currently in my engineering thesis trying to implement in a FPGA a CIC Interpolation Filter. I've recentrly finished the design in fixed point using DSP Builder and i want to test my design and compare it with the CIC Megacore Function Block.
This is what the documentation say: http://www.alteraforum.com/forum/attachment.php?attachmentid=13307&stc=1 I read the documentation and tried to figure out how to connect the inputs of the CIC Megacore Function Block for a simple output. This is what i implemented: http://www.alteraforum.com/forum/attachment.php?attachmentid=13306&stc=1 But this is what i get: http://www.alteraforum.com/forum/attachment.php?attachmentid=13308&stc=1 The input signal is a sin wave but i only get square signal as output of the filter. I have MATLAB R2015a and DSP Builder 16.0.1.218 running on Windows 7 64bit.Link Copied
