Syntax conventions

These syntax elements are used within all ModelSim command documentation:

Comments in argument files loaded with -f <filename>

Argument files may be loaded with the -f <filename> argument of the vcom, vlog,

and vsim commands. The -f <filename> argument specifies a file that contains

more command line arguments. It allows complex arguments to be reused without

retyping.

Comments within the argument files follow these rules:

• All text in a line beginning with // to its end is treated as a comment.

• All text bracketed by /* ... */ is treated as a comment.

Also, program arguments can be placed on separate lines in the argument file, with

the newline characters treated as space characters. There is no need to put '\' at the

end of each line.

Note: Neither the prompt at the beginning of a line nor the <Enter> or <Return> key that ends a line is

shown in the examples.
