    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.

    It happens on all designs and only on Linux-Systems on Winows it works just fine. But I added a design anyway, thought it doesn't matter, as said happens to all designs. Also error msg seems to be Quartus internal.
