SIMetrix provides the capability to export simulation data to a file in text form and also to import data from a file in text form. This makes it possible to process simulation data using another application such as a spreadsheet or custom program.
In this topic:
OpenGroup /text data.txtThis will read in the file data.txt and create a new group called text$n$, where $n$ is an index as described in Data Files Text Format below for details of format.
Note that if you create the file using another program such as a spreadsheet, the above command may fail if the file is still open in the other application. Closing the file in the other application will resolve this.
Show /file data.txt vout r1_p q1#cwill output to data.txt the vectors vout, r1_p, and q1#c. The values will be output in a form compatible with OpenGroup /text.
In the above example the vector names are vout, r1_p and q1#c. If you simulate a schematic, the names used for voltage signals are the same as the node names in the netlist which in turn are assigned by the schematic's netlist generator. To find out what these names are, place the mouse cursor on the node of interest on the schematic then press ctrl-S. The node name - and therefore the vector name - will be displayed in the command shell. A similar procedure can be used for currents. Place the mouse cursor on the device pin of interest and press ctrl-P.
Shell /wait procdata.exewill launch the program procdata.exe and will not return until procdata.exe has closed.
There are two alternative formats.
The first is simply a series of values separated by whitespace. This will be read in as a single vector with a reference equal to its index.
The second format is as follows:
reference_name ydata1_name[ ydata2_name ... ]Each datapoint must be of the form:
reference_value ydata1_value[ ydata2_value ... ]The number of entries in each datapoint must correspond to the number of entries in the header.
The reference is the x data (e.g. time or frequency).
Time Voltage1 Voltage2 0 14.5396 14.6916 1e-09 14.5397 14.6917 2e-09 14.5398 14.6917 4e-09 14.54 14.6917 8e-09 14.5408 14.6911 1.6e-08 14.5439 14.688 3.2e-08 14.5555 14.6766 6.4e-08 14.5909 14.641 1e-07 14.6404 14.5905 1.064e-07 14.6483 14.5821If the above was read in as a text file (using OpenGroup /text), a new group called textn where n is a number would be generated. The group would contain three vectors called: "Time", "Voltage1" and "Voltage2". The vectors "Voltage1" and "Voltage2" would have a reference of "Time". "Time" itself would not have a reference.
