    Hi @ost,


    Noted with thanks for the explanation and your patients, after some discussion alignment, unfortunately yes you are right. Short answer to global method of hls_singlepump are not possible at the moment for post compilation.

    Please do let us know if there is anything else we can clarify with.


    Regards

    BB

Hi BB

The answer at 13-09-2023 does not answer my question in a clear manner. I need to know if there is a global way to do hls_singlepump to prevent any possible 2x clock interface. There is no way to tell if arrays will be implemented as single or doublepump until compiled and verified. I already know that I can apply hls_singlepump to arrays, but pre compilation, I can not tell what arrays will be implemented in memory, registers or even flattened out and removed. I just need to tell the compiler to stay away from 2x clock domain in general, because my architecture does not have a 2x clock available.

I guess the answer to my question is no then.
