SystemVerilog增强了寄存器型变量的功能,它可以像Verilog中线网型变量一样由线网(如逻辑门等模块的输出)驱动(这样的线网驱动寄存器的方式在Verilog中是不允许的)。这种增强的变量类型被命名为“逻辑型”,从而避免“寄存器型”在字面上给人带来的误会。在大多数情况中,SystemVerilog中的logic可以替代Verilog中的reg和wire...
For example, a 4-by-2 matrix in Simulink is converted to a one-dimensional array of eight elements in SystemVerilog. These subsystems do not support DPI testbench generation: Triggered subsystem Enabled subsystem Subsystem with action port Component Testbench The SystemVerilog DPI component ...
DPI是System Verilog HDL中用于实现设计内部不同层次之间交互的一种机制。它允许高层次的设计模块访问低层次的设计模块,以便在仿真过程中对设计进行控制和观察。在这个过程中,任务是DPI的一种基本组成单位。 接下来,我们来讨论任务返回值的概念和应用。在System Verilog HDL中,任务返回值是指任务执行后产生的结果数据...
Simulink subsystem using HDL Coder, you can generate a SystemVerilog testbench in the form of a set of vectors. This testbench compares the output of the HDL implementation against the results of the Simulink model captured from simulation runs (SeeVerify HDL Design Using SystemVerilog DPI Test...
Then, use the dpigen function to generate your component. Select a built-in template for common component kinds, or create your own custom template. For an example that uses this template engine, see Use Templates to Create SystemVerilog DPI and UVM Components....
