Simulation
When you run a simulation, your circuit is translated into a Sonnet project and em is evoked.
For an ABS sweep, the analysis engine analyzes the circuit at the beginning and end frequencies. Using an iterative process, the solver then analyzes at other discrete frequencies and determines a rational polynomial fit to the S-parameter data within the frequency band. Once a rational polynomial fit is achieved with an acceptable error, the frequency response across the specified bandwidth is calculated.
The output data consists of the discrete data points, frequencies at which the solver performs a full electromagnetic analysis, and the adaptive data, which is data calculated using the rational polynomial.
To analyze your circuit, do the following:
If your circuit needs to be translated before analysis, a query window appears on your display. Click on the “Yes” button in the query window to translate your circuit before performing the simulation.
The simulation is launched. Updates of the simulation appear in the bottom of the Sonnet Cadence Virtuoso Interface window and the CIW, as shown below.
After the simulation is complete, continue the tutorial.
