fuse Overview and Syntax

ISE Simulator (ISim)

Note The following information is intended for advanced users.

Fuse is the HDL compiler, elaborator and linker used by the ISim. It links design units already compiled with vhpcomp or vlogcomp, and creates a simulation executable. Fuse also takes a mixed language project file and compiles the design units on the fly. Name(s) of the top-level design unit(s) must be specified on fuse command line argument. Fuse effects static elaboration on the design given the top design units and then compiles the design units to object code. The design unit object codes are then linked together to create a simulation executable.

Use the -top option to point to precompiled VHDL or Verilog, and use the -prj option to point to a project file listing VHDL or Verilog source files that you want included in your design.
Note The compiler (vhpcomp or vlogcomp) must pass the -top option to fuse or fuse will error out.
Use the -prj option to call vhpcomp or vlogcomp, as appropriate, and to compile your HDL code.
Use the -o <sim_exe> option to changes the simulation executable file name and location from the default x.exe.

Fuse generates object code and data files for each design unit comprising the design and places them inside isim/_tmp directory.

Caution Do no remove the isim/_tmp directory otherwise the design cannot be simulated.

The syntax for this command is as follows:

fuse (option )

where option is any option found in fuse Options.

Note This command is case sensitive.
