禁用协议允许外部模型参与SystemVerilog禁用处理。参与方法是通过DPI task的特殊返回值和特殊API调用来完成。特殊的返回值不需要更改SV代码中导入或导出DPI task的调用语法。虽然仿真器保证了导出task的返回值,但对于导入task,DPI另一侧必须确保返回正确的值。对导入task的调用与对SV原生task的调用是无法区分的。同样,对...

但DPI也支持both task and function,[2]p445也有提到,“VCS declared exported tasks as void functions in C.”,in sum, C side 不能消耗仿真时间。 我猜想这里所指的utilities应该是包括VCS中的TLI的。 补注:Although SystemVerilog provides different methods (PLI, VPI, DPI, etc) to support communications...
In particular, this paper will demonstrate a virtual prototype using the modeling interface provided by the SystemVerilog "DPI-C" construct that bridges the C software world with Verilog Hardware Description Language (HDL) world. Additionally, this paper will explain mec...

There is no difference in argument passing between calls from SystemVerilog to C and calls from C to SystemVerilog, apart from the fact that functions exported from SystemVerilog cannot have open arrays as arguments. Formal arguments in SystemVerilog can be specified as open arrays only in import...
In the experiments, the DPI interface technology in System Verilog is used to implement calls to Cor C++ code in the verification platform. Complex reference models are implemented by writing C functions, and floating-point multiplication and addition operations are written by using...
