2.3.1. Importing and Exporting for PCB Tools

The Pin Planner supports import and export of assignments with PCB tools. You can export valid assignments as a .pin file for analysis in other supported PCB tools. You can also import optimized assignment from supported PCB tools. The .pin file contains pin name, number, and detailed properties.

Mentor Graphics* I/O Designer requires you to generate and import both an .fx and a .pin file to transfer assignments. However, the Intel® Quartus® Prime software requires only the .fx to import pin assignments from I/O Designer.
