Setting Simulation-Control Properties

---

The Hierarchy Editor lets you set simulation-control properties that are used by Cadence applications such as the AMS simulator in your configuration.

You can set those properties that have been registered by a Cadence application in the property dictionary. The property dictionary is a central repository of property definitions; it comprises application-specific property dictionary files located in the your_install_dir/share/cdssetup/registry/props/ directory as well as user property dictionary files, if any. The Hierarchy Editor, by default, lets you display and set all the properties that are in the property dictionary.

You can also set properties that are not in the property dictionary by creating new property columns for them. These are typically properties that you use frequently with an application but that have not been registered in the property dictionary by the application. The Hierarchy Editor saves information about the new property columns in the configuration view in a file named prop.cfg.

You can set properties globally for an entire configuration or on cells, instances, or occurrences. Properties are also inherited by the hierarchy below the object on which they are set, unless the property definition specifies that it cannot be inherited.

The Hierarchy Editor stores the values of all the properties that you set in the prop.cfg file in the configuration view of your design. The prop.cfg file is read by other applications, such as simulators, that use the properties.
