phase margin in spectre ade

[shibinpv]

How to measure the phase margin of a two stage opamp using the ade calculator?

There is an analysis option "stb" (stability) which with the iprobe
"widget" does it all; you can plot traditional Bode plots or a margin
summary.

Otherwise it's make the gain expression, use the "cross"
function to find the zero gain, use that value as the argument
for value() on the phase expression.

At least, I've found no "canned" function.

There is a "phaseMargin" function.
