Sensitivity simulation - changing the file output format

[EstebanD]

Hello,

I am using version 6.3E and I am thinking of migrating to version 10. I am testing the sensitivity function.

I wonder if I can set the format of the files I get at the end of the sensitivity simulation with version 10.

In version 6.3E, I get a .tab file where the first line is the simulation number, the second the variable used for sensitivity and the following lines are the variables selected in the savelist file with their values for each simulation.

In version 10, three files are created:
-A .cin file named "*_fp_err"
-A vdfx file containing all the results of the sensitivity simulation (which can be quite a large file, around 1.1 GB in my case)
-A .tab file named "*_sens_trace" which is similar to the file obtained from version 6.3E, except that the variables are in columns rather than rows.

I joined some samples

. I have the following questions:
1/Is it possible to obtain a "*_sens_trace" file with variables in columns?
2/Can we select which file we want to obtain? For instance, only the "*_sens_trace" file.
3/About the .cin file, I suppose it is an error log, but what type of errors are highlighted? I only see variables equal to a specific value, but I do not know what that means.
4/How do I convert a "*_sens_trace" .tab file in a vdfx file?

Thank you for your reply.

Not any more. You can easily do what you need in Excel though.

3/About the .cin file, I suppose it is an error log, but what type of errors are highlighted? I only see variables equal to a specific value, but I do not know what that means.

The FP means floating point error. During your sensitivity, you had some floating point errors. If you run the sim with the FP CIN file, it will recreate the error so you can fix it.

4/How do I convert a "*_sens_trace" .tab file in a vdfx file?

Sorry, I don't understand what you want to do here.
