Print statements with subcircuits

Omar123318

Hello, I have a question regarding spectre netlist language

I know If I have a circuit containing MOSFETs, I can use a print statement to save specific parameter value to a file with the following statment:

print M0:vth,
+name = dc addto = "myfile.txt"

I wonder How can I use do the same If my mosfet now is defined inside subcircuit I? 

I see nothing about this in spectre help

    You would use:

    print I1.I4.M0:vth ...

    Where I1.I4.M0 is the hierarchical path of instance names down to the transistor in question.

    Thank you very much. This is really helpful. 

    I wonder if there is a way to print all MOSFETs' operating points in certain subcircuit using print statement?

    Dear Omar122318,

    I wonder if there is a way to print all MOSFETs' operating points in certain subcircuit using print statement? 

    The following link provides a means of printing all the DC operating points of the devices in your circuit.

    I hope this provides what you were hoping to accomplish!

    No, I want to do it from the netlist not the gui.

    Perhaps the simplest would be just to add:

    myoppoint info what=oppoint where=file file="myoppoint.txt"

    to your netlist. This will save all operating point info for every device into the specified file. As with other spectre instances/analyses, you can use whatever word you like for instance name of the info analysis as long as it is unique.

    Regards,

    Andrew.

    If I do it this way, can I filter the parameters to be printed?

    No. You could probably also use the print statement approach with wildcards for the component name.
