some doubt about pyspice alter command

[zhoujingfighting]

Hello:

I noticed two awesome functions: alter_device() and alter_model() but I did't find any examples about how to use them. I'm not sure what should the device_name be. For example, there is a capacitance named C1 in the . If I want to alter the value of C1, the device_name of C1 should be C1 directly or a chain like 'X1.foo.bar.C1`?

exactly , what I mean is that how pyspice kown the exact device or model name(ngspice manual:17.5.3) to alter parameters?

I will attach an example:
