Current Quartus Issues and FAQs
5/10/11
Known Issues
- 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.
- 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
- The project name and top most design file must be the same name.
- Take care to create a separate directory for each project. Mixing
projects in the same directory can cause unpredicatble problems.
- The UCF file pin names must match the names must match the input
and output port names used in your schematic or Verilog.
- Be sure to specify the correct the device type in Quartus or you
may get an unknow pin location error.
- 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.
