WebVerilog 提供了很多可以对文件进行操作的系统任务。. 经常使用的系统任务主要包括：. 文件开、闭：$fopen, $fclose, $ferror. 文件写入：$fdisplay, $fwrite, $fstrobe, $fmonitor. 字符串写入：$sformat, $swrite. 文件读取：$fgetc, $fgets, $fscanf, $fread. 文件定位：$fseek, $ftell, $feof, $frewind ... WebVerilog File Operations. Verilog has system tasks and functions that can open files, output values into files, read values from files and load into other variables and close files. This application describes how the Verilog model or testbench can read text and binary files to load memories, apply a stimulus, and control simulation.

Files should be opened in the write w mode, or append a mode. System tasks like $fdisplay() and $fwrite()can be used to write a formatted string into the file.

To read a file, it has to be opened in either read r … See more A file can be opened for either read or write using the $fopen() system task. This task will return a 32-bit integer handle called a file descriptor. This handle should be used to read and … See more In the previous example, we used $fgets() system task twice to read two lines from the file. SystemVerilog has another task called $feof()that … See more By default a file is opened in the write w mode. The file can also be opened in other modes by providing the correct mode type. The following table shows all the different modesa file can be opened in. See more SystemVerilog has another system task called $fscanf()that allows us to scan and get certain values.
