基于Protel99 SE的十进制加法器的仿真

Design and Simulation of Decimal adder Based on Protel99 SE

为了提高学生学习的兴趣和教学效果,同时验证电路设计的合理性。以十进制加法器为例,利用Protel绘制出仿真电路图;对图中的元器件进行参数设置和对仿真电路进行仿真设置,利用其ERC功能对电路设计不合理的地方加以改进得出仿真结果,验证所设计电路的正确性;所设计电路可以完成其电路功能,实现十进制的加法功能。

In order to improve the students＇ interest in learning and the teaching effect, at the same time to verify the theoretical of the circuit design. In this paper, the decimal adder is an example. Using Protel draw the simulation circuit; Attribute is set on the components in the graph and the simulation circuit simulation Settings, use the ERC function of Protel to improve the circuit rationality, at the end to simulate in order to validate the circuit function. Simulation results show that the designed circuit can complete the circuit function, and achieve the function of decimal addition.
