This chapter introduces ModelSim's VHDL FLI (Foreign Language Interface). For a categorical listing of FLI functions, see "FLI functions by category" . For complete details on the functions including purpose, syntax, and usage, see "FLI function definitions" .

Note: The Tcl C interface is included in the FLI; tcl.h is found in the <install_dir>/modeltech/include directory. Tk and Tix are not included in the FLI because the FLI is in the kernel, not the user interface. You can FTP Tcl from the Scriptics, Inc. web site.
