FPGAs of an Altera Max II FPGA The main product lines from Altera are the
Agilex FPGA product lines, and their predecessors: the high-end
Stratix series, mid-range Arria series, and lower-cost Cyclone series; as well as the MAX series non-volatile FPGAs.
Semiconductor intellectual property cores Altera and its partners offer an array of
semiconductor intellectual property cores that serve as building blocks that design engineers can drop into their system designs to perform specific functions. IP cores eliminate some of the time-consuming tasks of creating every block in a design from scratch. In 2000, Altera acquired Designpro and Northwest Logic, providers of IP cores, in order to expand its design capabilities and move towards delivery of complete system-on-chip solutions.
System on a chip FPGAs Beginning in December 2012, the company announced the shipment of its first
system on a chip FPGA devices using a fully depleted
silicon on insulator (FDSOI) 28 nm chip manufacturing process. These are the Cyclone V SoC devices, which have a dual-core
ARM architecture Cortex-A9 processor system with FPGA logic on a single chip. These devices integrated FPGAs with full hard processor systems based around ARM architecture onto a single device. With these SoCs devices, users were able to create custom field-programmable SoC variants for power, board space, performance and cost optimization. As of 2025, the majority of Altera's FPGA devices are available as an SoC variant with an ARM hard processor system integrated with the FPGA as a single system on a chip. Cyclone V SoC, Arria V SoC and Arria 10 SoC product families are system on a chip FPGAs based upon a hard
ARM Cortex-A9 dual-core processor system. Stratix 10 SoC and Agilex 7 SoC product families are system on a chip FPGAs based upon a hard
ARM Cortex-A53 quad-core processor system. The Agilex 5 SoC product family are system on a chip FPGAs based upon a hard
ARM Cortex-A76/
A55 quad-core processor system. The Agilex 3 SoC product family are system on a chip FPGAs based upon a hard
ARM Cortex-A55 dual-core processor system.
Soft Processor cores Altera offers the
Nios V embedded soft processor cores based on the
RISC-V instruction set architecture. Previously Altera had offered their own proprietary
Nios II embedded soft processor, the Freescale
ColdFire v1 core, and the
ARM Cortex-M1 processor.
Design software All of Altera's devices are supported by a common design environment, the
Quartus Prime design software, which is a multi-platform development environment that includes various tools needed to design FPGAs, SoC FPGAs, and CPLDs. In May 2013, Altera made available an SDK for OpenCL, enabling software programmers to access the high-performance capabilities of programmable logic devices. Altera also supports high-level synthesis using
SYCL extensions to ANSI C/C++. ==Intel partnership, acquisition and ownership==
