1.1 历史和基本特点随着电子技术的飞跃发展和各种新型电子元器件的不断涌现,现代电子电路日益向高频、多功能化方向发展,结构也变得越来越复杂,这使得传统的利用硬件面包板对设计进行验证的方法变得越来越不可行。而计算机硬件和软件技术的发展,使得只要用户能建立适当而精确的电路模型,就可以利用已知的电路理论和计算方法在计算机上利用软件建立一个虚拟的电路模型,并对其进行大量且迅速的计算,“仿真”出接近真实的电路结果。这种利用软件面包板的形式对电路设计进行验证的方法可以克服上述硬件试验方法所面临的困难,使得设计人员的精力更多地集中在设计层面,从而大大地节省产品开发的费用
1.1 History and Basic Features With the rapid development of electronic technology and the continuous emergence of various new types of electronic components, modern electronic circuits are increasingly being developed in high-frequency and multi-functional directions. As a result, the structure becomes more and more complicated, The use of hardware breadboards to validate designs has become increasingly unfeasible. The development of computer hardware and software technology makes it possible to build a virtual circuit model on the computer by using known circuit theory and calculation methods and to perform a large number of Quick calculation, “emulation ” comes close to the real circuit result. This method of verifying the circuit design in the form of software breadboard can overcome the difficulties of the above hardware test methods and enable designers to concentrate more on the design level so as to save the cost of product development greatly
