Constraining Logic and Assigning Pins

The tools in the Efinity® main window help you design the logic portion of your design. You use the Interface Designer to constrain logic and assign pins to the blocks in the periphery. In the Interface Designer, you connect the signals from your logic design to the pins in the device interface blocks, and then output a constraint file. During compilation, the Efinity® software uses the constraint file to constrain your design to the interface blocks.
