I am trying to implement 8 tap (7th order) Low Pass fir filter in ASIC semi custom design by writing its verilog code & testbench .. How do I represent the filter coefficients in the code ( which may be +/- ve and have fractional parts) ..?
Can I write direct statements (...)

I'm doing a project on altera quartus, where I need to implement a fir low pass filter in direct form. I was just about finishing writing it up, when I came to the realization that what I've done is not direct form (I don't think). My code is below, and I was wondering if anyone could suggest (...)

If u can get the book "Digital signal processing with field programmable gate arrays", I think there are a few examples of verilog code for fir filter design.

Here is a way to test ur fir filter...
1. Get VHDL or verilog code for fir filter ready.
2. Generate data file for (sine+ noise) using C or any other scripting file.
This you can do in C simply as follows..
for (i=0; i< (...)

4 tap filter eqn for ur design is:
y = (-1 * Tap0) + (3.75 * Tap1) + (3.75 * Tap2) + (-1 * Tap3)
while Rearranging it looks like:
y = +
- Tap3 +
Now Correlate this with ur verilog code:
y <= (tap
