Download and run the checksum sample design described in the SOPC Builder Memory Subsystem Development Walkthrough chapter in volume 4 o the Quartus II Handbook. Overview SOPC Builder is a powerul system development tool. SOPC Builder enables you to deine and generate a complete system-on-a-programmable-chip (SOPC) in much less time than using traditional, manual integration methods. SOPC Builder is included as part o the Quartus II sotware. You may have used SOPC Builder to create systems based on the Nios II processor. However, SOPC Builder is more than a Nios II system builder; it is a general-purpose tool or creating systems that may or may not contain a processor and may include a sot processor other than the Nios II processor. SOPC Builder automates the task o integrating hardware components. Using traditional design methods, you must manually write HDL modules to wire together the pieces o the system. Using SOPC Builder, you speciy the system components in a GUI and SOPC Builder generates the interconnect logic automatically. SOPC Builder generates HDL iles that deine all components o the system, and a top-level HDL ile that connects all the components together. SOPC Builder generates either Verilog HDL or VHDL equally. In addition to its role as a system generation tool, SOPC Builder provides eatures to ease writing sotware and to accelerate system simulation. This chapter includes the ollowing sections: Architecture o SOPC Builder Systems on page 1 2 Functions o SOPC Builder on page 1 5 Operating System Support on page 1 6 Talkback Support on page 1 7 March 2009 Altera Corporation Quartus II Handbook Version 9.0 Volume 4: SOPC Builder

1 2 Chapter 1: Introduction to SOPC Builder Architecture o SOPC Builder Systems Architecture o SOPC Builder Systems SOPC Builder Modules An SOPC Builder component is a design module that SOPC Builder recognizes and can automatically integrate into a system. You can also deine and add custom components or select rom a list o provided components. SOPC Builder connects multiple modules together to create a top-level HDL ile called the SOPC Builder system. SOPC Builder generates system interconnect abric that contains logic to manage the connectivity o all modules in the system. 1 This document reers to components as the class deinition or a module, while module is the instance o the component class. SOPC Builder modules are the building blocks or creating an SOPC Builder system. SOPC Builder modules use Avalon interaces, such as memory-mapped, streaming, and IRQ, or the physical connection o components. You can use SOPC Builder to connect any logical device (either on-chip or o-chip) that has an Avalon interace. There are dierent types o Avalon interaces, as described in the Avalon Interace Speciications. For details on the Avalon-MM interace reer to System Interconnect Fabric or Memory-Mapped Interaces in chapter in volume 4 o the Quartus II Handbook. For details on the Avalon-ST interace, reer to the System Interconnect Fabric or Streaming Interaces chapter in volume 4 o the Quartus II Handbook. For details about the Avalon-ST interace protocol, reer to Avalon Interace Speciications. Example System Figure 1 1 shows an FPGA design that includes an SOPC Builder system and custom logic modules. You can integrate custom logic inside or outside the SOPC Builder system. In this example, the custom component inside the SOPC Builder system communicates with other modules through an Avalon-MM master interace. The custom logic outside o the SOPC Builder system is connected to the SOPC Builder system through a PIO interace. The SOPC Builder system includes two SOPC Builder components with Avalon-ST source and sink interaces. The system interconnect abric connects all o the SOPC Builder components using the Avalon-MM or Avalon-ST system interconnect as appropriate.

Alternately, a component can act as an interace to an o-chip device, such as the DDR2 interace component in Figure 1 1. In addition to the Avalon interace, a component can have other signals that connect to logic outside the SOPC Builder system. Non-Avalon signals can provide a special-purpose interace to the SOPC Builder system, such as the PIO in Figure 1 1. These non-avalon signals are described in Conduit Interace chapter in the Avalon Interace Speciications. Available Components Altera and third-party developers provide ready-to-use SOPC Builder components, including: Microprocessors, such as the Nios II processor March 2009 Altera Corporation Quartus II Handbook Version 9.0 Volume 4: SOPC Builder
