SystemVerilog DPI Example Calling C++ method from SystemVerilog file Calling SystemVerilog method from C++ file SystemVerilog DPI (Direct Programming Interface) is an interface which can be used to interface SystemVerilog with foreign languages. These Foreign languages can be C, C++, SystemC as well...

In this example, you use a sine wave MATLAB function as a design under test (DUT), and follow the steps to generate a SystemVerilog DPI component by using the built-in sequential DPI template. After generating a SystemVerilog DPI component, you generate a UVM scoreboard by using...
if you set thehas_coverageflag to true in the YAML script, the UVMF code generator instantiates the coverage collector component in the agent. This agent uses the DPI code for the stimulus subsystem
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...
and run simulation. But Cadence NC seems need C code compile and link to a lib. I have read the NCsim document and find a switch "-sv_lib". But I cannot find a simple example. Is there any step by step tutorial about how to compile, link and run SystemVerilog DPI C file in ...
See Verify HDL Design Using SystemVerilog DPI Test Bench (HDL Coder). Both types of testbenches require a Simulink Coder™ license and the ASIC Testbench for HDL Verifier add-on. Limitations HDL Verifier converts matrices and vectors to one-dimensional arrays in SystemVerilog. For example, ...

7.DPI a.DPI= Direct Programming Interface 直接编程接口。 b.Verilog的PLI为其提供了一个可以调用C程序的机制,实际上每个使用verilog作为设计语言的大项目都会使用到verilog的PLI。 c.PLI可以全面地访问仿真数据的内部,如波形显示、图像化调试等,但DPI不可以。
