1.6.2. Connecting Masters and Slaves

Specify connections between master and slave components in the Address Map tab. This tab allows you to specify the address range that each memory-mapped master uses to connect to a slave in a Platform Designer system.

The Address Map tab shows the slaves on the left, the masters across the top, and the address span of the connection in each cell. If there is no connection between a master and a slave, the table cell is empty. In this case, use the Address Map tab to view the individual memory addresses for each connected master.

Platform Designer enables you to design a system where two masters access the same slave at different addresses. If you use this feature, Platform Designer labels the Base and End address columns in the System View tab as "mixed" rather than providing the address range.

To create or edit a connection between master and slave IP components:

  1. In Platform Designer, click the Address Map tab.
  2. Locate the table cell that represents the connection between the master and slave component pair.
  3. Either type in a base address, or update the current base address in the cell. The base address of a slave component must be a multiple of the address span of the component. This restriction is a requirement of the Platform Designer interconnect, which provides an efficient address decoding logic, which in turn allows Platform Designer to achieve the best possible fMAX.
