EDSpice Interactive Interpreter

If the user would like to simulate directly from a SPICE netlist of *.CIR format without creating the Schematic, which is why it is called the EDSpice Interactive Interpreter. Open a New project and launch EDSpice simulator. Now select Simulation | EDSpice Interactive Interpreter menu OR click on the button .

By default the commands required for running simulation is set. The commands for selecting analysis and its settings should be present in the SPICE netlist file. The user may select an existing SPICE netlist by clicking on the Open Circuit button. A new SPICE netlist may also be created by selecting the New / Edit Circuit Button (creating a new spice netlist is possible only if no SPICE netlist file is loaded).

Given below is a brief description of the parameters in the above window.
Commands Text area where interactive commands may be entered. Library paths, name of source and commands will be displayed in this section.
Simulation Status Displays the status of simulation indicating whether simulation had been successfully completed or whether any error was encountered.
Simulation Message Displays error messages that had occurred during simulation, if any.

Open Circuit Opens a SPICE netlist file (*.CIR). An open dialog box appears, browse to the required location and select the file.

Simulate Click on this button to run the simulation. The simulator will run the analysis which is set in the selected .CIR file and plot the results. If the CIR file contains the .PLOT command, the output will be presented in File Viewer.

If the CIR file contains the .SAVE command, it will plot the results in Waveform Viewer.


Click SIMULATE to execute the analysis. Once simulation is complete, the window will be as shown below.

New / Edit Circuit If no project is loaded, a new SPICE netlist file opens a New EDSpice Circuit File dialog, the name to which the new SPICE netlist has to be saved to is to be entered in this dialog. If a file is already loaded (this will be indicated by a Source line in the Commands text box, for e.g. ) source D:\EDS_WRK\AMPLIF.CIR that particular file will open in File Viewer. This may be then edited by the user.
Export to Waveform Viewer exports the rawfile to Waveform Viewer.
