Quartus Help For Beginner

[Altera_Forum]

Hi 

 I'm a student working on a circuit involving the epm7064 chip. I created the software a while ago, however I needed to add an additional output pin. I added it in the block diagram as well as in the pin planner. When I program the device and test the output signal I do not get anything. Am I forgetting to add the pin info in another file? Thanks in advanced

Check you quartus synthesis warnings regarding the new pin, to make sure it isn't getting optimized out or placed on a different pin. It could be getting optimized out do to a misconnection (ie no clock) or placed on a different pin if there's a mismatch between the name you put in the pin-planner and the name in your block diagram.

thanks for the response. As far as I can tell everything you mentioned above is correct.

Couple of ideas: 

 What programming file are you generating ? Check that has actually been updated and that your settings haven't been modified somehow  Did the assembler actually run ? I've seen cases where it didn't after changes like this.  Check the project.pin file generated by the fitter and look for your new pin  Change the settings to generate a simulation output verilog file (.vo file). Then read the resulting .vo file with a text editor and see if your new pin is there and connected to what you think it is.
