Performing a P2D Simulation

Start by creating your design, then add current probes and identify the nodes from which you want to collect data. For a successful analysis:

• Add the P2D control component to the schematic and double-click to edit it. Fill in these fields under the Freq tab:
  • Specify the name of the .p2d file. This is where the S-parameters that are generated by the simulation will be saved. The .p2d file will be saved in the project in the same location where dataset (. ds ) files are saved ( /data directory), unless you specify a path.
  • Select a sweep type. For a single point, enter the frequency. For a linear or logarithmic sweep, elect to define the frequency sweep with start/stop or center/span values.
• For a power sweep, fill in these fields under the Power tab:
  • Select a sweep type. For a single point, enter the power level for that point. For a linear or logarithmic sweep, define the power levels of the sweep with start/stop or center/span values. Power is in dBm.
• The P2D control component can extract noise characteristics to the . p2d file. You can control this noise characterization and other simulation parameters by placing an Options component on the schematic. For more information, refer to the topic "Using the Options Component" in the chapter "Simulation Basics" in the Using Circuit Simulators documentation.
• You can perform budget calculations as part of the simulation. For more information on budget analyses, refer to the chapter "Using Circuit Simulators for RF System Analysis" in the Using Circuit Simulators documentation.
• You can apply the Krylov subspace solution option for faster calculations of circuits with large numbers of nonlinear devices or large numbers of harmonics. Do not select this option for one-tone or power-sweep problems. See the topic "Selecting a Solver" in the chapter "Harmonic Balance Basics" in the Harmonic Balance Simulation documentation for instructions on how to use this option.
• You can use previous simulation solutions to speed up the simulation process. For more information, see the topic "Reusing Simulation Solutions" in the chapter "Harmonic Balance Basics" in the Harmonic Balance Simulation documentation.
