SystemVerilog_DPI
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
