1.3.2.1.1. Generating Signal Activity Data for Power Analysis

Follow these steps to generate and use simulation signal activity data for power analysis:

  1. To run full compilation on your design, click Processing > Start Compilation.
  2. To specify settings for output of simulation files, click Assignments > Settings > EDA Tool Settings > Simulation. Select your simulator in Tool name and the Format for output netlist and Output directory.
  3. Turn on Map illegal HDL characters. This setting directs the EDA Netlist Writer to map illegal characters for VHDL or Verilog HDL, and results in more accurate data for power analysis.
