专用可编程集成电路（ASICApplicationSpecificIntegratedCircuit）是速度快、集成度高、用户可编程的逻辑器件。近几年，在数字系统和计算机外围接口电路设计中ASIC得到了广泛的应用。本文给出的用PLA模型设计时序逻辑电路的方法不同于传统的时序电路设计方法，更适用于ASIC实现时序逻辑电路。文中给出了经过仿真和验证、功能正确的设计实例电路。
Application Specific Integrated Circuit (ASICApplicationSpecificIntegratedCircuit) is fast, highly integrated, user-programmable logic device. In recent years, ASIC has been widely used in digital system and computer peripheral interface circuit design. The method of using PLA model to design sequential logic circuit is different from the traditional sequential circuit design method, which is more suitable for ASIC implementation of sequential logic circuit. The article gives the circuit of design example after simulation and verification.
