OpenBus System - Configuring Interconnect Components
Configuration of an Interconnect component is performed using the Configure OpenBus Interconnect dialog (Figure 1).
Figure 1. Configuring an Interconnect component.
If you are familiar with configuration of the WB_INTERCON component in the schematic world, you will no doubt appreciate the reduced level of information required to configure the Interconnect component. The OpenBus System handles much of the configuration 'behind the scenes' as it were, so information such as data bus width, addressing mode and device type no longer require user-definition.
There is no manual addition/deletion of devices to/from the Interconnect. If a link exists between a peripheral and the Interconnect, the device will automatically be listed in the dialog.
There is also no manual definition of the Master Address Size. This too is taken care of in the background, dependent on which port of the processor the Interconnect is linked – IO (24-bit) or MEM (32-bit).
There are, in fact, only three pieces of information required to complete the configuration of the Interconnect for each slave device – the Base Address, the Decoder Address Width and the Address Bus Size. Default information for each comes directly from the peripheral component itself.
