Xilinx Command Line Tools User Guide: (UG628)

Chapter 1: Introduction
Command Line Syntax
Command Line Options
Command line syntax always begins with the command line program name. The
program name is followed by any options and then by file names. Use the following
rules when specifying command line options:
• Enter options in any order, preceded them with a dash (minus sign on the keyboard)
and separate them with spaces.
• Be consistent with upper case and lower case.
• When an option requires a parameter, separate the parameter from the option by
spaces or tabs. For example, the following shows the command line syntax for
running PAR with the effort level set to high:
– Correct: par -ol high
– Incorrect: par -olhigh
• When using options that can be specified multiple times, precede each parameter
with the option letter. In this example, the -l option shows the list of libraries to
search:
– Correct: -l xilinxun -l synopsys
– Incorrect: -l xilinxun synopsys
• Enter parameters that are bound to an option after the option.
– Correct: -f command_file
– Incorrect: command_file -f
Use the following rules when specifying file names:
• Enter file names in the order specified in the chapter that describes the command
line program. In this example the correct order is program, input file, output file,
and then physical constraints file.
– Correct: par input.ncd output.ncd freq.pcf
– Incorrect: par input.ncd freq.pcf output.ncd
• Use lower case for all file extensions (for example, .ncd).
The following options are common to many of the command line programs provided
with the ISE® Design Suite.
• -f (Execute Commands File)
• -h (Help)
• -intstyle (Integration Style)
• -p (Part Number)
-f (Execute Commands File)
Syntax
With any Xilinx® command line program for use with FPGA designs, you can store
command line program options and file names in a command file. You can then execute
the arguments by entering the program name with the -f option followed by the name
of the command file. This is useful if you frequently execute the same arguments each
time you execute a program or if the command line command becomes too long.
-f command_file
