Examples
Formulas to quickly set device utilization and evaluate thermal effects when varying device, package or cooling parameters:

= INT(NUM_LUTS * 0.75) Sets total LUT utilization to 75% of device capacity (if entered on the Logic sheet)

= INT(NUM_DSPS * 0.90) Sets DSP block utilization to 90% of device capacity (if entered in DSP sheet)
