Compiling and linking PLI/VPI applications

ModelSim Verilog uses operating system calls to dynamically load PLI and VPI applications when the simulator loads a design. Therefore, the applications must be compiled and linked for dynamic loading on a specific operating system. The PLI/VPI routines are declared in the include files located in the ModelSim <install_dir>/modeltech/include directory. The acc_user.h file declares the ACC routines, the veriuser.h file declares the TF routines, and the vpi_user.h file declares the VPI routines.

The following instructions assume that the PLI or VPI application is in a single source file. For multiple source files, compile each file as specified in the instructions and link all of the resulting object files together with the specified link instructions.
