FIR compiler reload coefficients

Jump to solution

Hello everyone,

I am using a FIR compiler with the configuration bellow, but I am having an issue with the coeficients reload :

I configured the FIR to have 128 coefficients, but I have an asserted "event_s_reload_tlast_missing" flag after only writing half the coefficients (64). I'am writing one coefficient with each clock rising edge(160 MHz), is this the right way to do it ?

Any suggestion or idea is welcome

Thank you !

If anyone is having the same issue :

It's because of the configuration I chosed, my .coe file containes symetric coeffcients therefore I am guessing that I was expected to only send half the coeffcients.
