4.5. Plan for Standard Interfaces

To reduce design iterations and costly design changes, plan for use of standard interfaces in system design. Using standard interfaces ensures compatibility between design blocks from different design teams or vendors.

You can use the Intel® Quartus® Prime Interface Planner to help you accurately plan constraints for design implementation. Use Interface Planner to prototype interface implementations and rapidly define a legal device floorplan.

Standard interfaces simplify the interface logic to each design block, and enable individual team members to test their individual design blocks against the specification for the interface protocol to ease system integration.

You can use the Intel® Quartus® Prime Platform Designer system integration tool to use standard interfaces and speed-up system-level integration. Platform Designer components use Avalon® standard interfaces for physical connections, allowing you to connect any logical device (either on-chip or off-chip) that has an Avalon® interface. Platform Designer allows you to define system components in a GUI, and then automatically generates the required interconnect logic, along with clock-crossing and width adapters.

The Avalon® standard includes two interface types:

  • Avalon® memory-mapped—allow a component to use an address-mapped read or write protocol that connects master components to slave components.
  • Avalon® streaming—enables point-to-point connections between streaming components that send and receive data using a high-speed, unidirectional system interconnect between source and sink ports.
