   <abstract xml:lang="ru">
    <p>Статья посвящена разработке отечественного САПР, предназначенного для проектирования различных цифровых устройств микроэлектроники. Представленные работы проведены ФГБОУ ВО «ВГЛТУ» совместно с холдингом РОСЭЛЕКТРОНИКА. Использовано программное обеспечение Cadence, позволившее осуществить моделирование цифрового микропроцессора, основанного на 32-х битном ядре SCR1 компании SYNTACORE с реализацией набора команд IMC. Синтезирование RTL модели для тестирования произведено в автоматическом режиме и включало в себя этап проверки на синтезабельность и этап непосредственно синтеза. Синтез осуществлён в базисе стандартных библиотечных элементов выбранной технологии для технологического процесса фабрики HHGRACE. Для созданной модели произведено тестирование списка соединений (netlist), при этом логическая модель заменялась списком цепей. Затем осуществлён расчёт потребляемой схемой мощности. В завершении разработки, для уже готовой модели проведены разнообразные тесты, направленные на проверку корректности RTL кода, – тесты на соответствие спецификации, тесты на краевые случаи (corner case testing), тесты на основе прикладных задач и алгоритмическое тестирование (real code testing), а также тесты на пиковую производительность и пропускную способность коммутаторов и интерфейсов.</p>

    <p>The article is devoted to the development of a proprietary CAD system designed for the design of various digital microelectronics devices. The presented works were carried out by VSFEU in cooperation with ROSELECTRONICS Holding. Cadence software was used to simulate a digital microprocessor based on SYNTACORE's 32-bit SCR1 core with the implementation of the IMC instruction set. The synthesis of the RTL model for testing was carried out in automatic mode and included a stage of testing for synthesizability and a stage of direct synthesis. The synthesis was carried out on the basis of standard library elements of the selected technology for the 130 nm process of the HHGRACE factory. For the created model, a test of the connection list (netlist) was performed, while the logical model was replaced by a list of circuits. Then the calculation of the power consumed by the circuit was carried out. At the end of the development, various tests aimed at verifying the correctness of the RTL code were carried out for the ready-made model - tests for compliance with specificity, tests for edge cases (corner case testing), tests based on applied tasks and algorithmic testing (real code testing), as well as tests for pico-high performance and throughput of switches and interfaces.</p>
