3.2.3.2. Extended LUT Mode

Figure 11. Supported 8-Input Functions in the Extended LUT Mode

You can implement certain 8-input functions in a single ALM using all the LUT inputs:

  • datae
  • datad0
  • datac0
  • dataa
  • datab
  • datac1
  • datad1
  • dataf

In the 8-input extended LUT mode, the packed register mode is supported, provided that the packed register shares a dataa or datab input with the 8-input LUT.
