System Contents Tab (View Menu) (Qsys)

You open this tab by clicking View > System Contents. The System Contentstab appears by default when you open a new system in Qsys.

The System Contents tab displays the components that you add to your system and allows you to specify connections and parameters at the interface level. You can select the columns you want to display by right-clicking any column header on the System Contents tab. The System Contents tab has the following columns:

Use—Allows you to enable or disable component instances in your system. Disabled components do not appear in the generated system.
Connections—The connectivity for each component instance.
Description—The description of the component or interface.
Clock—The clock source for each clock interface on a component instance.
Base—The base address for each memory-mapped slave port.
End—The end address for each memory-mapped slave port.
Name—The name for each component instance.
Export—Allows you to export an interface for use outside the system.
Auto Export—Allows you to export all interfaces of an instance for use outside the system. If the parameterization of the instance adds or removes interfaces, the exported interfaces is updated automatically.
Tags—User-defined values for use with filters.
Security—Allows you to designate a master component as Secure, Non-secure, Secure ranges, or TrustZone-aware.
Default Slave—Allows Qsys to reroute transactions that violates security.
Opcode Name—Displays a Nios II custom instruction opcode name for a custom instruction interface.
IRQ—The interrupt number (if any) for each interrupt sender.
