Pin-Out File (.pin) Definition

An ASCII text file (with the extension .pin) that contains pin assignments and other pin information for the device you specified for a design in the current Compiler settings. The Pin-Out File, which the Fitter generates, has the same name as the Compiler settings and contains the Compiler settings name; the device you specified for the design in the Compiler settings; the pin assignments for the device; and the I/O standard, voltage setting, and pin type of the pins. Use Right-click > Find in the .pin file to locate items in the file.

Note:
  1. When you change the design files for a set of Compiler settings, the Fitter may change the pin assignments for the device. To retain the current pin assignments for future compilations, back-annotate the assignments.
