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:
Working with LabVIEW Filtering VIs and the LabVIEW Digital Filter Design Toolkit VIs

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