在数字集成电路领域里,特别是随机逻辑电路,随着集成度的不断提高,电路的专用性越来越强。然后,供专门系统用的全专用电路的缺点是设计周期长,研制费用昂贵,又不适合小批量生产。为了填补标准系列产品与全专用电路间的空白,就出现了门阵列电路,它以设计周期短,研制费用低,又不受品种和数量限制等优点受到广泛的欢迎,因此它已成为大规模数字集成的主流。
In the field of digital integrated circuits, especially the random logic circuit, with the continuous improvement of integration, the circuit is more and more specialized. Then, the disadvantage of a fully dedicated circuit for a specialized system is the long design cycle, the expensive development, and not suitable for small batch production. In order to fill the gap between the standard series and the all-purpose circuit, there is a gate array circuit which has been widely popularized due to its short design cycle, low development cost, unlimited variety and quantity limit, etc. Therefore, it has become a large-scale The mainstream of digital integration.
