|
|
| 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. |
