The basic structure of code we will follow for creating a testbench to test the design is as follows:module design_name_tb (); //internal registers and wires reg <reg_names>; // All design inputs should be registers wire <wire_names>; // All design outputs can be wires //initialize...
This is due to the fact that timing analysis tools always have problems with latches; glitch at enable pin of latch is another problem). One simple way to eliminate the latch with always statement is to always drive 0 to the LHS variable in the beginning of always code as shown in the...

概念 当我们完成一个比较完整的系统的时候,通常需要编写一个Testbench来验证自己的设计的功能能否满足设计要求.在这个系统中通常会有一个top模块来连接那些小的模块,verilog通过实例化的方式来完成这些子模块和顶层模块的连接,然后顶层模块可以由此来调用各个子模块. 用法 调用模块的端口一般有两种方式,一种是位置关联,...
