Altera Quartus II is a programmable logic device design software produced by Altera. Quartus II enables analysis and synthesis of HDL designs, which enables the developer to compile their designs, perform timing analysis, examine RTL diagrams, simulate a design's reaction to different stimuli, and configure the target device with the programmer. Quartus includes an implementation of VHDL and Verilog for hardware description, visual editing of logic circuits, and vector waveform simulation.
Quartus II software features include:
- SOPC Builder, a tool in Quartus II software that eliminates manual system integration tasks by automatically generating interconnect logic and creating a testbench to verify functionality
- Qsys, a system-integration tool that is the next generation of SOPC Builder. It uses an FPGA-optimized network-on-chip architecture that doubles the fMAX performance vs. SOPC Builder.
- SoCEDS, a set of development tools, utility programs, run-time software, and application examples to help you develop software for SoC FPGA embedded systems.
- DSP Builder, a tool that creates a seamless bridge between the MATLAB/Simulink tool and Quartus II software, so FPGA designers have the algorithm development, simulation, and verification capabilities of MATLAB/Simulink system-level design tools
- External memory interface toolkit, which identifies calibration issues and measures the margins for each DQS signal.
- Generation of JAM/STAPL files for JTAG in-circuit device programmers.
SOPC Builder (System on a Programmable Chip Builder) is software made by Altera that automates connecting soft-hardware components to create a complete computer system that runs on any of its various FPGA chips. SOPC Builder incorporates a library of pre-made components (including the flagship Nios II soft processor, memory controllers, interfaces, and peripherals) and an interface for incorporating custom ones. Interconnections are made though the Avalon bus. Bus arbitration, bus width matching, and even clock domain crossing are all handled automatically when SOPC Builder generates the system. A GUI is the only thing used to configure the soft-hardware components (which often have many options) and to specify the bus topology.
The resulting "virtual" system can then be connected to the outside world via the FPGA's programmable pins or connected internally to other soft compoments. The FPGA's pins are routed to connectors, such as for PCI or DDR, or—as is often the case in embedded systems—to other chips mounted on the same PCB.
Resource utilization on an FPGA hosting an SOPC Builder system is very modest by modern standards. FPGA devices supporting SOPC systems include almost all Altera FPGAs (and even some CPLDs) ranging from $5 to $5,000 in price.
The Web Edition is a free version of Quartus II that can be downloaded or delivered by mail for free. This edition provided compilation and programming for a limited number of Altera devices.
The low-cost Cyclone family of FPGAs is fully supported by this edition, as well as the MAX family of CPLDs, meaning small developers and educational institutions have no overheads from the cost of development software.
License registration is required to use the Web Edition of Quartus II, which is free and can be renewed an unlimited number of times.
The Subscription Edition is also available for free download, but a DRMed license must be paid for to use the full functionality in the software. The free Web Edition license can be used on this software, restricting the devices that can be used.
The supported operating systems are:
- Microsoft Windows Vista (32-bit and 64-bit)
- Microsoft Windows XP (32-bit and 64-bit)
- Microsoft Windows 2000
- Solaris 8 and 9 (32-bit and 64-bit)
- SUSE Linux Enterprise 9 (32-bit and 64-bit)
- Red Hat Enterprise Linux 5 (32-bit and 64-bit)
- Red Hat Enterprise Linux 4 (32-bit and 64-bit)
- Red Hat Enterprise Linux 3 (32-bit and 64-bit)
