么？
答：一个完整的EDA工程通常要涉及到系统建模、逻辑综合、故障测试、功能仿真、时序分析、形式验证等内容。而对于设计工程师而言，系统建模中的器件模型有生产厂商给出，工程师只需要完成系统设计、逻辑综合、布局布线、仿真验证和下载测试几个步骤。 5.简述ASIC设计和CPLD/FPGA设计的区别？
答：专用集成电路(ASIC)采用硬接线的固定模式，而现场可编程门阵列 (FPGA)则采用可配置芯片的方法，二者差别迥异。可编程器件是目前的新生力量，混合技术也将在未来发挥作用。
6.阐述行为仿真、功能仿真和时序仿真的区别？
答：行为仿真只考虑逻辑功能。功能仿真仅仅完成了对VHDL所描述电路的逻辑功能进行测试模拟，以观察其实现的功能是否满足设计需求，因而仿真过程并不涉及任何具体器件的硬件特性。时序仿真则是比较接近真实器件运行的仿真，在仿真过程中已经对器件的物理模型参数做了恰当的考虑，所以仿真精度要高得多。 7.详细描述EDA设计的整个流程？ 答：
系统规格制定（Define Specification） 设计描述（Design Description） 功能验证（Function Verification） 逻辑电路合成（Logic synthesis）
逻辑门层次的电路功能验证（Gate-Level Netlist Verification） 配置与绕线（Place and Routing）
绕线后的电路功能验证（Post Layout Verification） 8.为什么要进行硬件电路的后仿真验证和测试？
答：后仿真考虑了实际器件的模型参数，能够更好的模拟实际电路工作状态。测试是检验设计合格的最直接的方式。
