资料介绍

DPI:Direct Programming Interface An interface between System Verilog and a foreign programming language:C or C++

■Simple interface to Cmodels

·Allows SystemVerilog to call a C function just like any other native SystemVerilog function/task

·Variables passed directly to/from C/C++

·NO need to write PLI-like applications/wrappers

■Why DPI?

·SystemVerilog users have C/C++in designs and testbench that they want to reuse

·DPI easily connects C/C++ code to SV without the overhead or complexity of VPI/PLI

■Support both functions and tasks

.SystemVerilog can call C and C can call SV

DPI Vs. TLI

■TLI

· Transaction Level Interface in VCS for SystemC-

SystemVerilog transaction level co-simulation

· SystemC calling SystemVerilog interface functions/tasks for class methods

· SystemVerilog call SystemC interface methods

, Blocking or non-blocking

· Under the hood, TLI is implemented with DPl

. But easier to use

. Automatically synchronizes between the SystemC domain and SystemVerilog
