UM-566 D - Verilog PLI / VPI / DPI DPI use flow Steps in flow ModelSim SE User’s Manual Correct use of ModelSim DPI depends on the flow presented in this section. .v vlog vsim vlog -dpiheader dpiheader.h vsim exportobj.o 1 Run vlog (CR-358) to generate a dpiheader.h file. This file defines the interface between C and ModelSim for exported and imported tasks and functions. Though the dpiheader.h is a user convenience file rather than requirement, including dpiheader.h in your C code can immediately solve problems caused by an improperly defined interface. An example command for creating the header file would be: vlog -dpiheader .h dpiheader.h vsim -dpiexportobj exportobj.o mtipli.lib Step 4 Simulate vsim -sv_lib Step 1 Create header Step 1.5 Windows only .so shared object ld/link loader/linker Step 2 Include header #include "dpiheader.h" .c gcc C compiler .o compiled user code Step 3 Compile and load/link C code
For Windows only: Run a preliminary invocation of vsim (CR-373) Because of limitations with the linker/loader provided on Windows, an step is required. You must create the exported task/function compiled object file (exportobj.o) by running a preliminary vsim command, such as: vsim -dpiexportobj exportobj.o 2 Include the dpiheader.h file in your C code. ModelSim recommends that any user DPI C code that accesses exported tasks/functions, or defines imported tasks/functions, will include the dpiheader.h file. This allows the C compiler to verify the interface between C and ModelSim. 3 Compile the C code into a shared object. Compile your code, providing any .a or other .o files required. For Windows: In this step, the object file is bound into the .dll that you created using the -dpiexportobj argument. 4 Simulate the design. When simulating, specify the name of the imported DPI C shared object (according to the SystemVerilog LRM). DPI use flow UM-567 ModelSim SE User’s Manual
