Beginning with version 25.1.1 of the Quartus® Prime Pro Edition software, pin location assignments and I/O standard assignments are required for a programming file to be generated. If these required assignments are missing, no programming file is generated. You must add the required assignments and recompile your design to generate a programming file. If you do not want to generate a programming file, you may ignore this behavior change.
To determine whether your design is missing pin location or I/O standard assignments, review your compilation messages. If either of the following messages was generated during your compile, your design is missing pin location or I/O standard assignments that are required to generate a programming file:
- Critical Warning: Some pins have incomplete I/O assignments. Refer to the I/O Assignment Warnings report for details
- Critical Warning: No exact pin location assignment(s) for <number> pins of <number> total pins. For the list of pins, please refer to the I/O Assignment Warnings table in the fitter report
Review the I/O Assignment Warnings report, found in the Place sub-section of the Fitter section of the compilation report. Alternately, review the <revision>.fit.plan.rpt report file. For any pins in the I/O Assignment Warnings report that are reported as “Missing location assignment” or “Missing I/O standard,” add the appropriate location or I/O standard assignment. For help making these assignments, refer to Assigning I/O Pins
After adding any required assignments, recompile the design to generate a programming file.
This change applies to all device families supported by the Quartus® Prime Pro Edition software, beginning in version 25.1.1. Missing pin location or I/O standard assignments are reported as a critical warning, not an error. If you script the compilation of projects, the exit code of the compilation process still indicates success even if pin location or I/O standard assignments are missing, because missing pin location or I/O assignments are reported as a critical warning, not an error.
