Hi,I'm new in VHDL, I'm intend to design a filtr typ FIR. I have used Megafunction in Quartus. But it supports only 37 taps for each fir. I need about twice taps of that. I'm thinking about connect 2 filtrs serial, or design one filtr by myself using Matlab to canculate coeficients and write it in vhdl. By your experiments, can you give me some advice, should I write it myself or using 2 megafunction filters. Or any another suggestion. Which of those is most optimal for speed, resource...:confused: :confused: :confused: Thank you!!!
