Hi
I am trying to include a sub circuit into my VHDL code. But quartus gives me the following error: design library "work" does not contain primary unit "PwmOut", this happens when I move the whole subfolder in the working directory, and also when only the sub project file is moved into the directory. I have also tried to include the VHDL sub file into the project, but this gives me a lot of errors to.
(I have followed this tutorial: VHDL coding tips and tricks: Entity Instantiation - An easy way of Port mapping your components )

My question is how should the sub circuit files be include into the working directory when using quartus?
 

My guess is one of a few:

You haven not included pwmout.vhd in your project
you have compiles your module before you compiles pwmout
PwmOut is not in a file called Pwmout.vhd
the entity is not called Pwmout.

one of many things. Just including the file is not enough.
 

Hi

I included PwmOut.Vhd and compiled PwmOut before PwmController was compiled, now quartus finds the file but I get some errors on the In and Out Signals on the Port map. I have attached my code, how I want the circuits to corporate, and my including.

Could I have misunderstood the use of a subcircuit in VHDL? Ie that all in and outs of a subcircuit has to be connected to the main circuit, and not the way I am using it with two of the subcircuit out ports connected to I/O ports.

to include your design in quartus:
1)go to 'Assignment / Setting'
2) in the category list (on the left) go to 'Files'
3)and browse your file and click add files the click OK.

hopefully this is what you need..
