ieee float and fixed point packages

[GD76]

Included the ieee.fixed and float as shown below in top.vhdl. The files are in Quartus/ieee/2008 folder.

library ieee;
use ieee.fixed_pkg_vhdl2008.all;
use ieee.float_pkg_vhdl2008.all;

In compilation, the following error and not sure what these means.

Error (10481): VHDL Use Clause error at PDA_361000893_TOP_FPGA.vhd(31): design library "ieee" does not contain primary unit "fixed_pkg_vhdl2008". Verify that the primary unit exists in the library and has been successfully compiled.

Hi,

Did you add those libraries to your project? Go to Assignments>Settings>Libraries to add them.

Also, which Quartus version are you using? VHDL 2008 are only supported on certain Quartus versions: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/po/ss-quartus-comparison.pdf

I tried that and got an error. So removed that and added straight in VHDL file  the following and worked.

library ieee_proposed;
use ieee_proposed.fixed_float_types.all;
use ieee_proposed.fixed_pkg.all;

The error is about the library not compiled. But don't know how to compile the ieee library. Thanks anyway.
