If the results of a simulation are not what you expect to see, the bias conditions are the first parameters you should check. After simulating with PSpice, you can display bias point information on your schematic page in Capture. Bias voltages are displayed next to their corresponding nets (nodes), bias currents are displayed next to their corresponding device pins and the bias powers are displayed next to their corresponding power sources. By seeing this data on your schematic, you can quickly focus in on potential problem areas of your design. PSpice calculates and saves the bias point current, voltages and powers for every simulation. Capture reads all of this information and can display currents on all pins that have models, voltages for every net in your circuit or powers for every power source in your circuit. Note: Bias point information is available for all analysis types except DC Sweep. The bias point display feature does not work for DC Sweeps. You can choose to display bias point information in the following ways: ■ currents on all modeled pins throughout the design ■ currents on only selected modeled pins ■ voltages on all wires throughout the design ■ voltages on only selected wires ■ powers on all power sources throughout the design
