Setting up a Full-Wave SPICE Analysis

To determine a suitable frequency range for a solution that are used for a Full-Wave SPICE analysis:

  1. Click Setup Full-Wave Spice in the sweep setup window to open the Setup for Full-Wave Spice window.
  2. Type a value in the Signal Rise Time field. This value represents the time scale that characterizes the rate of change of the input time signal to be applied in the circuit simulator. By default, this value is set to 1.
  3. Type a value in the Time Steps Per Rise Time field. By default, this value is set to 5. The time sampling increment for the entire signal is calculated using: where
    • is the time sampling increment.
    • is the signal rise time.
    • is the number of time steps per signal rise time.
  4. Enter a value in the Number of Time Points field. By default, this value is set to 500. The input time signal duration is determined using: where N is the number of time points.
  5. Click Calculate. The Electronics Desktop determines the Maximum Frequency using: where Fmax is the maximum frequency. It determines the Frequency Step Size using and determines the Number of Frequency Steps using N-1.
  6. Click Accept to transfer the new frequency sweep data to the frequency sweep fields in the sweep setup window.
    • Optionally, click Cancel to return to the sweep setup window and maintain previously entered frequency sweep settings.
