IEEE library showing up in red

Altera_Forum · ‎02-09-2017

Hi,

I just started programming in VHDL for a computer architecture class and I was wondering if it was normal that when I type in: library IEEE; use IEEE.STD_LOGIC_1164.all; it shows up as:

library IEEE; use IEEE.STD_LOGIC_1164.all;

In the examples I have, the whole line shows up in blue. Does it mean the library isn't working?

Thanks!

It seems that if it is a built in library/packet, the name will be red in quartus. If it is something you write by your own and attached in the work folder, the name will be blue.
