Рассмотрен метод косимуляции, позволяющий использовать часть моделируемого микропроцессора в виде абстракции более высокого уровня, тем самым сокращая нагрузку на вычислительные машины и время моделирования.</p></abstract><trans-abstract xml:lang="en"><p>In the development of high-performance microprocessors, low abstraction level modeling creates a large load on computing machines and takes a lot of time.
