Parametric Analysis

(Analysis Menu)

The parametric analysis within Microwind is a powerful tool for rapid investigation of the effect of some parameter variation on the behavior of the circuit. An example of analysis may be the effect of the load capacitance on the delay of a gate. The parametric analyzer will increase automatically the capacitance, run a set of simulations and plot the result on the screen.

- Click on Analysis -> Parametric Analysis

- Select the desired output node on which the delay measurement or frequency measurement is performed, then. Click on a cell output node in the layout. The parametric analysis window appears.

- In the parameter menu, choose the item "node capacitance". Give the appropriate range of analysis.

- In the measurement menu you may choose to monitor the rise and fall delay, the power consumption, or the frequency.

Click on " Start Analysis ". An iterative procedure will conduct simulations and extract the relevant parameters. Example results may show the evolution of the cell delay when its output node capacitance has been changed, or the influence of temperature variations on the final value of a polarization voltage.
