3.2.1. Generating Pin Assignment Files

You transfer I/O pin assignments from the Intel® Quartus® Prime software to the Mentor Graphics* PCB tools by generating optional .pin and .fx files during Intel® Quartus® Prime compilation. These files contain pin assignment information for use in other tools. Click Assignments > Settings > Board-Level to specify settings for optional PCB tool file generation. Click Processing > Start Compilation to compile the design to generate the file(s) in the project directory.

The Intel® Quartus® Prime-generated .pin contains the I/O pin name, number, location, direction, and I/O standard for all used and unused pins in the design. Click Assignments > Pin Planner to modify I/O pin assignments. You cannot import pin assignment changes from a Mentor Graphics* .pin into the Intel® Quartus® Prime software.

The .fx is an input or output of either the Intel® Quartus® Prime or I/O Designer software. You can generate an .fx in the Intel® Quartus® Prime software for symbol generation in the Mentor Graphics* I/O Designer software. an Intel® Quartus® Prime .fx contains the pin name, number, location, direction, I/O standard, drive strength, termination, slew rate, IOB delay, and differential pins. An I/O Designer .fx additionally includes information about unused pins and pin set groups.

The I/O Designer software can also read from or update an Intel® Quartus® Prime Settings File (.qsf). You can use the .qsf in the same way as use of the .fx, but pin swap group information does not transfer between I/O Designer and the Intel® Quartus® Prime software. Use the .fx rather than the .qsf for transferring I/O assignment information.
