How You Can Create an Application Image
When your OpenROAD application is ready to be run, you can create an image of the application. An application image is a version of an application that is stored in an operating system file outside of the database. The performance of an application is significantly better when it is run from an image than from the database.
Keep in mind that an image reflects the state of an application at the time you created the image. If you make any subsequent changes to the application, you must create a new image to incorporate those changes.
