Bandgap Startup Stability Analysis

To get the stability of startup circuit, you may want to know the stability information through a period of time. To do this:

Use Transient simulation operating point in stb analysis

Try using the Setup->Environment form, and looking at the "Analysis Order". You can enter "tran stb" in this field to tell it what order to do the analyses, which will override the default.

This makes the stability analysis use the final time of previously transient simulation as its operating point in calculating the stability information, as can been verified in spectre.out file.

Alternatively, you can set actimes & acnames in transient analysis:

The generated netlist reflect these changes by:

and the spectre.out shows something like:
