2.3. Importing and Exporting I/O Pin Assignments

The Intel® Quartus® Prime software supports transfer of I/O pin assignments across projects, or for analysis in third-party PCB tools. You can import or export I/O pin assignments in the following ways:

Table 5.  Importing and Exporting I/O Pin Assignments
 

Import Assignments

Export Assignments

Scenario

  • From your PCB design tool or spreadsheet into Pin Planner during early pin planning or after optimization in PCB tool
  • From another Intel® Quartus® Prime project with common constraints
  • From Intel® Quartus® Prime project for optimization in a PCB design tool
  • From Intel® Quartus® Prime project for spreadsheet analysis or use in scripting assignments
  • From Intel® Quartus® Prime project for import into another Intel® Quartus® Prime project with similar constraints

Command
