When you load a database, the design hierarchy is listed in the Design Browser sidebar. A design can contain pure analog, pure digital, or mixed-signal designs. Therefore, the tool uses different icons to identify the type of each design component listed in the Design Browser sidebar.
The following table describes the icons:
|
Indicates the top of a design hierarchy and is named simulator. |
|
Represents mixed-signal instances in the design. |
|
Represents the digital instances in the design. |
|
Represents the analog instances in the design. |
By default, the Design Browser sidebar displays all types of design component. You can use the Show/Hide Analog or Show/Hide Digital icons in the sidebar to selectively view only analog or only
digital components.
The following example shows digital components filtered out.
Alternatively, you can change the default visibility setting for analog and digital components by selecting or deselecting the check boxes on the Mixed tab in the Sidebar Options form.
Opening Multiple Databases
You can connect to only one simulation at a time. Therefore, by default, the Design Browser sidebar displays a single hierarchy.
When running a simulation, you might probe objects to one or more databases. These databases store all the information about the objects in the simulator design hierarchy.
You might also open any number of databases that contain the results of previous simulations. These databases are not connected to the simulator.
