$fmonitor(<file_handle>,"<string>", variables); 其中:file_handle为文件句柄,表示要对哪个文件进行写操作;string为写入文件的格式;variables为写入的数值。 $fmonitor和$monitor系统函数的使用类似,但只有variables 列表中发生变化,时间节点到达时,才执行函数。优点是,不必纠结在哪里打印输出, 只要触发条件,就可以...
当该时刻的所有事件处理完后在这个时间步的结尾打印一行格式化的文本规则这些系统任务的变量的语法和它们所写的文本和几乎和display任务一样当strobe被调用的时刻所有活动都完成了strobe才打印文本这包括所有阻塞性和非阻塞性赋值的作用monitor monitorvsdisplayvsstrobe ---verilog monitorvsdisplayvsstrobe:(从实验中了解)...
1、$display和$write:可以直接打印文本或变量值,$write执行后不自动换行。2、$strobe:与$display使用方式一致,但打印信息的时间有差异。$strobe在其他语句执行完毕后才执行显示任务,适合打印非阻塞赋值的变量值。3、$monitor:为监测任务,监测变量变化并在终端打印对应信息,使用方法与$display相同。dis...
两者的区别在于:$strobe命令会在当前时间部结束时完成;而$display是只要仿真器看到就会立即执行。 3、$monitor监测任务 监测任务用于持续监测指定变量,只要这些变量发生了变化,就会立即显示对应的输出语句。 eg: initial begin $monitor("x=%b,y=%b,cin=%b",x,y,cin); end 同理,有$monitor,$monitorb$monitor...
在SystemVerilog的Language Reference Manual(简称LRM)中,介绍了几种语言自带的打印函数,包括$monitor(),$strobe(),$write()以及平时最为常用的$display()。这几种打印函数看起来基本都是一样的,可是如果在写testbench时不注意使用场景,系统打印的值可能不会是你想要的值,从而对调试、验证过程造成阻碍。

My project is to display an image 640x480 (from SDRAM) on a monitor. I write the hardware by my own in Verilog. The structure of my design : SDRAM <-- DMA-50MHz ( Master read + slave control ) <--->50Mhz- asynchronous FIFO - 25Mhz <---> 16_to_...
