7.5.1. Logic Elements

An Altera® LE contains a four-input LUT, which is a function generator that can implement any function of four variables. In addition, each LE contains a register fed by the output of the LUT or by an independent function generated in another LE.

You can use the Resource Property Editor to view and edit any LE in the FPGA. To open the Resource Property Editor for an LE, on the Project menu, point to Locate, and then click Locate in Resource Property Editor in one of the following views:

  • RTL Viewer
  • Technology Map Viewer
  • Node Finder
  • Chip Planner

    For more information about LE architecture for a particular device family, refer to the device family handbook or data sheet.

You can use the Resource Property Editor to change the following LE properties:

  • Data input to the LUT
  • LUT mask or LUT
