ViVA re-simulate and plot again

I use this technique quite often - but it is not as reliable as I would like for a number of reasons that I will not discuss now. The procedure I use is as follows:

1. After formatting the plot in a format you like, save the plot as a ".grf" file by using the ViVA File->Save menu item. You will be prompted to save the file to some location in your workspace.

2. After saving the file, open the file with your preferred text editor.

3. Within the file, you will find lines that contain a UNIX path to the results directory from which you plotted the results. These lines (or lines adjacent to them) contain the signal names you are plotting as well as a number of formatting commands. Do a global replacement of the UNIX path to the results directory from which you plotted the results with the UNIX path to the set of new simulation results for which you want to use your plot template. Save the file with a different name ("new_data_plot.grf"?) to avoid overwriting your initial graph file. You may also want to globally replace the text you used in the title of the original plot with a new set of text to distinguish the new plot from the original plot.

4. From the ViVA window once again, from the File->Load menu item, navigate to and select your new file "new_data_plot.grf". This will open a new tab with waveforms from your new simulation results plotted in a similar format to the manner in which the original simulation data was plotted.

Let me know if you have any questions.

PS - I am not sure which version of ViVA you are using. With some earlier versions, when you navigate to the directory containing your new ".grf" file, the new file may not be visible in the ViVA browser. In this case, type the name of the new ".grf" file in the file selection box and it will then show up in the file selection window.
