Why does Agilex Power and Thermal Calculator count "Half ALMs"

The Agilex Power and Thermal Calculator in QPro 21.4 has a column in the Logic Summary labeled "# Half ALMs".

Why does it count 1/2 ALMs?

Is that because an ALM can be seen as the equivalent of 2x 4-input LUTs?

Thank you

  • Correct. Newer devices have many more options for how the LABs and ALMs can be configured, so if you're not using the full ALM, that saves power.
