Forum: Analog Circuits LTSpice - "Multiple Instances of Flag" Error

Hi,

I am trying to develop an RF circuit, but quite inexperienced with 
LTSpice. As much as I check out on Google, I could not find a solution 
to my problem, where the Run command for Transient analysis returns 
"Multiple Instances of Flag" error. I examined the model file with a 
text editor, but it was no use, I could not find a specific error.

It is probably because of my mistake that the model I use is not well 
connected by its model files to the schematic. The model I used for 
SA612 mixer and an ss is attached.

Anyone knows how can I get rid of this "Multiple Instances of Flag" 
error?

Hierarchical schematics didn't need the ".include" command.

Changing this line into a comment (and assigning a value to C6) the 
simulation runs without error messages using the automatically generated 
symbol.

If you encounter further errors, please attach your "SA612.asy" too.

Thanks for the reply,

It really works well.

Hi,

Iam trying to include the file LT3471 it end up showing multiple 
Instance of flag error. Help me to fix this error.

                               Thank you!

Why do you try to include a schematic? That's not possible. Copy the 
schematic into this schematic or make a hierarchical schematic.

Here are two diode data sheets. I want to focus on modeling SER30KE60 
because it has a lot of data.  The second data sheet provides 
definitions of typical reverse recovery parameters.



Tasks:



1. Write a .meas statement in diode test schematic that will find the 
diode peak reverse current.



2. Run a .meas script from the waveform viewer. Create a text file that 
has the same .meas statement and give it the ending .meas  The results 
are in the .log file



3. Run a .meas script from CMD.



4. Use Python to run a simulation, run .meas, and capture the peak 
reverse current from the log file.



the question is how to do this from datasheet without modeling a circuit

Pls start a new thread for a totally new question!
