2.4.4. Understanding I/O Analysis Reports

The detailed I/O assignment analysis reports include the affected pin name and a problem description. The Fitter section of the Compilation report contains information generated during I/O assignment analysis, including the following reports:

  • I/O Assignment Warnings—lists warnings generated for each pin
  • Resource Section—quantifies use of various pin types and I/O banks
  • I/O Rules Section—lists summary, details, and matrix information about the I/O rules tested

The Status column indicates whether rules passed, failed, or were not checked. A severity rating indicates the rule’s importance for effective analysis. “Inapplicable” rules do not apply to the target device family.
