When you run a "Live Simulation" in [[B2RF.Spice A/D]], the simulation results are typically displayed in real time using either [[Virtual Instruments|virtual instruments]] or circuit [[animation]] on your schematic. At the end of [[B2RF.Spice A/D]] [[Tests]], the simulation results are normally displayed using graphs, tables or both. [[B2RF.Spice A/D]] has a powerful "Data Manager" that can generate a variety of graphs types and tables for visualizing and displaying your test results. Some [[Virtual Instruments|virtual instruments]] allow you to record the simulation data during a live simulation and then plot them on a graph, too.
At the end of an analog or mixed-mode circuit simulations, the node voltages, branch currents and device powers are typically available for graphing or tabulation. Voltages, current and powers are usually plotted as a function of time or frequency. In the case of a Network Analysis test, port characteristics like scattering, impedance or admittance [[parameters]] are also computed. At the end of a digital circuit simulation, it is the state of the digital inputs and outputs that you would like to visualize.
The Edit Plot List dialog consists of three tables. The table on the left shows the hierarchy for the case of multilevel signals. In the middle table (Signal Name List) you see a list of the available signals for plotting. The table on the right (Graph Name List) lists the signals to be plotted. Select one of more signals from the middle table and use the right arrow "Add-->" button to move them to the right table. You can also select more than one signal using the "Ctrl" key or a range of consecutive signals using the "Shift" key. You may modify and revise the list of the signals to be plotted by moving one or more items from the right table back to the middle table using the left arrow "<--Remove" button.
Besides voltages, currents and powers, [[B2RF.Spice A/D]] allows you to define, calculate and graph or tabulate new custom plots. This is done using the two buttons labeled "Add Custom Plot" and "Edit Custom Plot". Both buttons open up the "Edit Signal Plot" dialog. Here you enter a name and color for your new plot. The dialog has three tables. On the left you see a list of all the available signal names. In the middle, you see a list of all the legal mathematical functions. On the right is a list of all the legal operators. You can define your new plot using a mathematical expression involving the available signals and the legitimate mathematical functions and operations.
