program block是一个对应的概念,它是给testbench引用的,存在的意义在于避免testbench中对module的引用引起竞争冒险问题,它是如何解决竞争冒险的呢,这就要回到systemverilog最开始的那篇时序上了,program里面对blocking和non blocking assignment的调用是在active region,NBA之后的reactive region。 它在使用上,大部分时候跟...
在程序块中要采用非阻塞赋值语句 (<=)对时钟(clocking_block)中的信号做驱动。在程序块中的本地变量进行赋值要采用阻塞赋值语句 (=)。程序块中可以有任务、函数、类和 initial块,但不能有always块。对封装验证程序的程序块采用 automatic来定义。程序块可以消除验证平台和设计之间的竞争。区别module里可以定义...

Several projects have been undertaken to map MatLab programs, or descriptions in the Simulink block-diagram format, into hardware. Banerjee et al. (2001) describe a compiler that maps MatLab programs onto a distributed system containing embedded processors, digital signal processors, and FPGAs. ...
IF, THEN, ELSE, and ENDIF should be used to conditionally change the flow of control in a program. Every IF line should be terminated with a THEN statement, and every IF block should be terminated with an ENDIF statement. Use of the ELSE statement is optional and depends on the applicatio...
If the process completes successfully, a green check mark displays next to Analysis & Synthesis. If you get an error, check your syntax and make sure it matches exactly the code block provided above. Be sure you used the “View Source” button when you copied the text in step 3.a above...
SV_13_Program Block 摘要:verilog中的module用于描述 硬件,它可以始终包含initial和assign语句。SV引入了program,其中包含了完整的测试平台 。 1。 program与module program 的目的: 为testbench提供接入点; 创建了一个域来封装program的数据、任务和函数; 便于资源在Reactive region的调度。 program不能包含always块...
