Write a testbench that instantiates this AND gate and tests all 4 input combinations, by generating the following timing diagram: from hdlbits 白话:给定一个与门模块,为这个模块编写testbench,并生成如图所示的波形图。 答案: moduletop_mod
This may seem unusually large, but I include in "verification" all debugging and correctness checking activities, not just writing and running testbenches. Every time a hardware designer pulls up a waveform viewer, he or she performs a verification task. With today's ASIC and FPGA sizes and ...

Testben使用的是硬件语言,而其 所依赖的环境却是基于PC的软件平台。这也就决定 了其独特的代码风格。有时的的确确是以一个软件式的顺序方式在给待测试硬件代码做测试,但是写出来的testbench代码中却时常布满了并行执行的陷阱。这给硬件测试者带来了不少麻烦,既然我 们选择了verilog,那么就得好好领会它在 硬件测...
in_use = 1’b0; end endtask 粗体部分就是加入了检错机制,用in_use作为task已被调用的标志信号,从而避免其它的调用。 Writing testbench——文件调用 最近在做一个FPGA工程的测试工作,接口比较繁杂。Testbench做起来更多的是感受到用Verilog做行为级设计的局限性。比如做一个CPU的读写时序,其实很难做到两个工程...

mental improvements during the same period. What is clearly needed in verification techniques and technology is the equivalent of a synthesis productivity breakthrough. In the second edition of Writing Testbenches, Bergeron raises the verification level
Writing Testbenches Using SystemVerilog introduces the necessary concepts and tools of verification, describes a process for planning and executing an effective functional verification project and outlines the concept of coverage models that can be used in a coverage-driven verification process. The book...
