A simulator can simulate anything ,a stall in particulare.
As it is the yardstik for any flght test and performance.
High alltitude test flights at full stall are not needed for sertificatiion and not always recovered. Thereby not required, and not documented by test data.
Have fully stalled a Jar25 aircraft many times at say 8000 feet, but no medium or large jet.
Computer says NO.
