Passing tcl script variables to qsf file

Hi,

Thanks for the example project.

Upon checking, the Intel Quartus Prime Standard and Lite edition software has limited VHDL-2008 language support. Reference: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/po/ss-quartus-comparison.pdf

I tried to run in the Pro edition software, the error did not occur.

Thanks.
