In this article, we will learn how we can use Verilog to implement a testbench to check for errors or inefficiencies. We’ll first understand all the code elements necessary to implement atestbench in Verilog. Then we will implement these elements in a stepwise fashion to truly understand the...
正常写缓冲时返回值 code 为 0,发生错误时返回值 code 为 EOF 按行读文件 code = $fgets(str, fd) ; 按字符连续读,直至变量 str 被填满,或一行内容读取完毕,或文件结束正常读取时返回值 code 为读取行数(次数),发生错误时 code 为 0 按格式读文件 code = $fscanf(fd, format, args) ; 按格式 forma...

A Verilog Testbench can be written by the following steps: 1. Declare top-level testbench module moduletb_latch;// All testbench code goes inside this moduleendmodule 2. Declare signals for DUT connection The latch design contains 3 inputs and 1 output. Inputs are declared of typeregso th...
Testbench文件编写纪要(Verilog) 之前在使用Verilog做FPGA项目中、以及其他一些不同的场合下,零散的写过一些练手性质的testbench文件,开始几次写的时候,每次都会因为一些基本的东西没记住、写的很不熟练,后面写的时候稍微熟练了一点、但是整体编写下来比较零碎不成体系,所以在这里简要记录一下一般情况下、针对小型的...
