Using PARAM in OrCad 10.0 Demo: The PARAM part can be used to allow sweeps of a component value. The component value must be a global variable, which is done by replacing the value with a variable name. Global names appear in { } in the circuit. For example to do a scan changing a resistor value, you change the resistor value from something like 1k to {Rload}. The PARAM part is then used to link that name to the simulation settings. Example: Select the component which will has the value that will be swept, for example select R1. Select the value that you wish to scan, for example 1k. Replace the value, 1k, with a name in curly brackets, {Rload}. Select and add the PARAM part to the schematic. It is in the Special library. Double click on the PARAM part.

Unformatted text preview: Click on “New Column” in tool bar, say yes to warning. In dialog box, enter the global value name in the “Name” box, Rload In “Value”, enter a nominal value, for example 1k Click ok A new column should now appear. Click on that column so that it is highlighted. Click on the “Display” button in the tool bar and display both name and value. Click on ok and close this window. You may add as many columns as desired. The PARAMETER part should now show something like Rload = 1k. Click on the Edit Simulation Settings icon. Analysis type: pick AC Sweep/Noise Click on Parametric Sweep Click on Global parameter and enter the parameter name, Rload Enter the sweep type and values Close the Simulation Settings box and run the simulation....
