Key words :verification;SystemVerilog;testbench;reusable 0 引言 随着集成电路设计复杂性的增加,验证的难度也日益加大。传统的基于Verilog的验证效率低、可重用性差,为此,工业界推出了具有面向对象特性、支持约束随机与断言等功能的标准化硬件描述与验证语言SystemVerilog[1]。 对SoC等大型设计的验证多采用基于方法学的...
由于inner_port和outer_port端口都是双向端口(在 VHDL和Verilog语言中都用inout定义),因此驱动方法与单向端口有所不同。 验证该双向端口的testbench结构如图2所示。 这是一个self-checking testbench,可以自动检查仿真结果是否正确,并在Modelsim控制台上打印出提示信息。图中Monitor完成信号采样、结果自动比较的功能。 te...

Verilog中的变量有线网类型和寄存器类型。线网型变量综合成wire,而寄存器可能综合成WIRE,锁存器和触发器,还有可能被优化掉。 二:verilog语句结构到门级的映射 1、连续性赋值:assign 连续性赋值语句逻辑结构上就是将等式右边的驱动左边的结点。因此连续性赋值的目标结点总是综合成由组合逻辑驱动的结点。Assign语句中的...
