FFT_FIR_Filter from OpenCore

[h_rafii]

Hi Every one.

i have found a core for fft based fir filter from Opencore and thanks to my friend Miralipor not it is works for spartan 6.

The Problem is that when we run the test bench, DATAE and DATAIRE and DATAIIM which are the data input for real and imaginary parts are Unvalid and unknown.

I linked the project in the below file.

https://github.com/abhinavgupta/FFT-FIR-Filter


please help me to solve it.

Does this mean it does not work for Spartan 6? I'm unsure what you were trying to say. My cranial English as a second language translation app had a segfault when reading that.

That usually means they aren't being driven by the testbench, but should be.

I attached the project ISE ot it in the below file.

...but as there is no project, I can't check.

please help me to solve it.

well it's kind of hard to do that, since I'm not a psychic.

yes,

it was not synthesiable for spartan 6, it was only worked with spartan 3 and verti files but one of my friend from Edaboard "Miralipoor" helped to solve it.
with adding "work." befor CONTROL() ==> U_CNTRL:entity work.CONTROL(CONTROL_SLIP)

helped to be synthesiable for spartan 6

Well I'm not going to cut and paste each file out of the webpage frames into .vhd files. IMO opencores' website has gotten more useless with "fluff" every time they make a change to it. I'm not interested enough in opencores to get a login and download the files.
