    I had this problem too with some versions of QuartusPro, at least 19.3, both on Linux Mint and CentOS, but could not find any answers in Jan-Feb.

    Today I found your posting and also this link: https://wikis.uni-paderborn.de/pc2doc/Noctua_FPGA_Usage,_Integration_and_Development

    which provide a possible explanation and fix.

    It is related to the linux LOCALE setting, if you use another format than US (in Europe, we use decimal comma, not point).

    By setting LC_NUMERIC= ="en_US.UTF-8", at least for the QuartusPro session, the problem disappears.

    Sorry for the delayed answer, I was an vacation for last 2 weeks.

    Well I tried compiling my test design using your patch on windows and it worked just fine.

    But during multiple tests (on linux) I noticed that even under linux the error won't always show up (and somtimes even result in multipe messages instead of just 1) so it might have been coincidence on windows.

    Anyway I noticed that Quartus 20.1 got released in the meantime, I haven't check the changlog yet, but I will give this version a try maybe it helps.
