Xilinx 7 series FPGAs currently mainly have four process levels, namely Spartan, Artix, Kintex and Virtex. So what are the characteristics of these four craft levels? Next, I will briefly introduce it.

1. The devices of the Virtex series not only represent the highest level of Xilinx, but are often the best devices in the entire FPGA industry. Devices in this series are generally used in high-speed networking (10G~100G), portable radar, and ASIC prototype verification. These fields are characterized by high requirements on the number of resources and performance, but are not very sensitive to power consumption and cost.

2. Compared with Virtex series devices, Kintex series devices have made certain concessions in cost and power consumption, and achieved a relatively good balance between cost, performance and power consumption, but the cost is still relatively high. Kintex devices are generally used in 3G/4G wireless communication, display and Video IO Over and other fields.

3. The Artix series devices greatly reduce the device cost without reducing the performance and the number of resources as much as possible. This series of devices is widely used in the domestic medical equipment and military industries.

4. The performance and the number of resources of the Spartan series devices are far inferior to the previous three series, but the advantage is that the price is cheap, so the devices of this series are relatively widely used in consumer electronics, automotive electronics and industrial fields. It is worth mentioning that the performance of Spartan series devices is much higher than that of Altera‘s Cyclone series (the benchmark with Spartan). For example, Spartan6 supports DDR3, but the Cyclone10 series, which was interviewed very late after that Neither supports DDR3.

The above are the four process-level features of Xilinx 7 series FPGAs, I hope they can help you for your reference.
