NAME
openroad - OpenROAD command-line-interface.
SYNOPSIS
openroad [-help] [-version] [-no_init] [-no_splash] [-exit] [-gui]
[-threads count|max] [-log file_name] [-metrics file_name] [-python]
cmd_file
DESCRIPTION
The openroad command is the command-line interface for OpenROAD, an
open-source initiative for chip design and optimization. It provides a
range of options to control its behavior and execute commands specified
in the cmd_file.
OPTIONS
-help: Display help information.
-version: Display version information.
-no_init: Skip initialization steps.
-no_splash: Do not show the license splash at startup.
-exit: Exit after executing commands in cmd_file.
-gui: Launch the graphical user interface (GUI).
-threads count|max: Specify the number of threads to use (or use max
available).
-log file_name: Log output to the specified file.
-metrics file_name: Save performance metrics to the specified file.
-python: Execute the cmd_file as a Python script.
ARGUMENTS
cmd_file: The command file containing OpenROAD commands to be executed.
EXAMPLES
openroad -help: Prints the help information
openroad -version -exit: Prints the version information, and exits the
program thereafter.
openroad -threads max -log test.log -metrics test.metrics: Prints the
log and metric respectively to test.log and test.metrics. Also runs
the script with maximum available number of threads.
openroad -gui: Launches OpenROAD GUI, which further interactive Tcl
commands can be run.
TCL COMMANDS
These Tcl-based commands are callable from within the OpenROAD binary.
• read_lef [-tech] [-library] filename
• Read Library Exchange Format (.lef) files.
• tech: Technology-specific information
