Entitled: "SwitcherCADIII(LTSpice) super utility is ready!",
Wrote the following:
|Hello to all users of LTSpice,
|I have written a utilty program that makes the LTSpice program
|even more useful.
|The features are:
|Merge as many raw files you want into one raw file.
|The advantage is that you can have different simulations in one graph.
|A raw file is the output file of a SPICE simulation. It conatins
|the numbers which are used for displaying the waveforms.
Built-in "Append" in PSpice Probe. Just be sure to rename the
appropriate .DAT files so they don't get over-written by subsequent
runs. I've been harping for a "Save as" in Probe, but have been
ignored :-( Charlie and Brian take note )
|Extract data to your spreadsheet or favorite graphic program for
|documentation or post processing.
|You select the signals you want and get a column based output.
As simple as ctrl-C, ctrl-V in Probe. I do this all the time putting
data into Excel.
|Equalize time steps of .TRAN simulation.
|Normally you have never exact the time steps you want in a raw file.
|This can become necessary if you want export data to other programs.
Set with "Print Step" in the Transient Analysis set up window of
PSpice Schematics; also can be done in Capture, but I don't know how
|These are the most important functions of the program.
|If you ever have experienced different simulations in one plot or
|easy exporting data to another graphic program, you will be impressed.
|I hope that in some future time, all these features are implented in
|Thanks to Mike Engelhardt for the great LTSpice and the support.
|The utility program can be downloaded from here. There is also a
|help file there.
|Enjoy the program!
|The SwitcherCADIII(LTSpice) program can be downloaded from
|the Linear Technology website http://www.linear.com/software/ .
