1.1. Power Analysis Tools

The Intel® Quartus® Prime Design Suite provides tools to analyze the power consumption of your FPGA design at different stages of the design process.

  • Early Power Estimator (EPE) spreadsheet—estimates power consumption for power supply planning before compiling the design.
  • Intel® Quartus® Prime Power Analyzer—estimates power consumption for a post-fit design, allowing you establish guidelines for the power budget.

Data outputs
Note: The EPE and Power Analyzer outputs vary by device family.
  • Total thermal power dissipation
  • Thermal static power
  • Thermal dynamic power
  • Off-chip power dissipation
  • Current drawn from voltage supplies
  • Total thermal power
  • Thermal static power
