Программы для разработки RF&Microwave устройств, Опросник "кто чем пользуется?" Опции

[Alex2172]

Моделирование одного устройства в разных пакетах, как ни странно, приводит к разным результатам. Это объясняется отличиями в представлении устройства в разных пакетах (например отличается представление "портов").
Вот и возникет вопрос, кто чему доверяет и как моделируемые параметры согласуется с измеряемыми?
