Current Quartus Issues and FAQs

5/10/11

Known Issues 

  1. Do not use the keyboard short cut CNTRL S to save files within Quartus. Instead, use the file save ICON. Using the keyboard short cut can cause the file to be non readable by Quartus.
  2. It is not possible to create a custom schematic symbol file directly from a schematic. It is necessary to convert the schematic to a Verilog file first, then convert the Verilog file to a schematic symbol. Both functions are found in Quartus under FILE-->Create/Update.

Common FAQs

  1. The project name and top most design file must be the same name.
  2. Take care to create a separate directory for each project. Mixing projects in the same directory can cause unpredicatble problems.
  3. The UCF file pin names must match the names must match the input and output port names used in your schematic or Verilog.
  4. Be sure to specify the correct the device type in Quartus or you may get an unknow pin location error.
  5. Do not name the schematic design file and testbench file the same name.

Archiving a Quartus Project

Sometimes the lab staff may not be able to address your problem during the lab. From time to time we encounter problems that can not be resolved during the lab time.Your lab instructor may ask you to archive the project and send it to him or her. They will take a look at later and have the lab staff review it. To archive a project in Quartus, under the Project Menu select Archive project. Confirm the process and when completed browse for a file with the your projects name and the extension .qar. Send this file to your lab instructor. You will be granted a breif extension until the problem is resolved.
