Hi Shotaro,
Yes, our macro-models are specifically designed to model stability of the circuit - please review following link:

The circuit stability with the capacitive load is a function of circuit configuration like gain and is typically shown in graph in terms of the small-signal overshoot - see below.
In order to assure stability over process and temperature variation, it is recommended to design the circuit for the maximum overshoot of 25%, which corresponds to 45 degrees phase margin. Simulating OPA322 driving directly (no Riso) 10nF load shows only 3 degrees phase margin - see below.
The marginal stability of OPA322 in G=1 may be confirmed by running transient simulation - this shows a small-signal overshoot of around 100% overshoot - see below.
In order to assure stable operation with recommended 45 degrees phase margin, it is necessary to add outside the close-loop 7ohom Riso resistor as shown below.
Transient simulation confirms stable operation with a small-signal overshoot of 19% - see below.
For your customer's convenience I have attached below Tina-TI simulation files for OPA322.
