FIR compiler for begginers

[Reuven.Stahl]

Hi all!

i'm new to FPGA , and i have a VI (i did not program it) that uses the FIR Vi to fliter an array of waveforms. i'm trying to re-write that VI in FPGA
instead of an array of 9 diffrent waveforms i have 9 diffrent 1D arrays (Each elamnt in the arrays is FXP (24,7)) 
i tried to save the filter data from the original VI to a txt file, then to make it into a .coe file, and to use this file with the 7.1 FIR compiler 
all i get after i do all the neccery conversions (from FXP to array of BOL for each point of data) is a False array, like nothing have happend
some expermints have thought me that issue may lay with the ACLK input of the FIR compiler VI, but i have no clew what am i doing wrong?

Any help (or hint's. or relvent data sheets/manuals/white papers) would be helpful

thanks in advance 🙂

I was able to find some potentially relevant resources on FIR that might be helpful as you debug:

Good luck!

An example VI with the FIR Compiler 7.x block in a SCTL, wired to IQ data would be sublime.

Hi,

I found such an example. It is in the High Throughput FPGA course though, exercise 5-1.

How you do it anyways? I can't understand where you aclk signal should be connected to

Hi,

Are you talking about the Xilinx IP in LabVIEW, FIR Compiler 7.x block?

Yes, the Fir compiler 7.2 to be exact!!!

I do not think the aclk signal needs to be connected.

Hi,

it's been a while, but can someone post the exercise 5.1?

Thank you.
