QCADesigner Documentation

Most QCADesigner objects have associated properties. To modify them, double-click on the object.

Cell Functions

The function of a cell can be changed by double-clicking on the cell. This will bring up the cell function dialog as shown below:

Normal Cell

A normal cell has no special function other then to exist and switch according to the influence of neighboring cells.

Fixed Polarization

A fixed polarization cell will remain at the chosen polarization during the simulation regardless of the effect of neighboring cells or the clock.

Input Cell

Input cells will have a polarization that is determined by the simulation engine. The input values will be set according to the Simulation Type. You can simulate all possible input combinations by choosing the Exhaustive Verification or select input vectors manually using a Vector Table.

Output Cell

Output cells act just like normal cells in that they are directly affected by their neighbors. The polarization of the output cells is recorded throughout the simulation and plotted in the graph dialog when the simulation is complete.

Clock

This allows you to change the clock for the selected cell.

Substrate properties

The grid spacing a substrate maintains can be changed by double-clicking on the substrate and specifying the desired grid spacing in its property dialog:

Label properties

The text of a label can be modified by double-clicking on it and typing it into its property dialog:
