What is xilinx FPGA?
Xilinx FPGA Is a field programmable logic array, most FPGA consists of programmable logic resources (LUT and REG), programmable line, programmable I / O.Xilinx The basic structure of the FPGA is the same, FPGA is in the PAL, PLA and CPLD programmable devices on the basis of further development of a more complex programmable logic devices, so xilinx fpga has low cost capacity, also focus on high performance products, users can choose according to their own needs, most of the FPGA is applied in the industrial field more.
Artix7
Artix ® -7 belongs to one of all XILINX FPGA type, similar to most FPGA, it contains logic, signal processing, embedded memory, etc. Artix-7 is a low power consumption, high performance FPGA, especially suitable for low power consumption, small size and high bandwidth applications, such as communications, industrial automation, medical devices, consumer electronics and automotive electronics.
How to read the naming rules of XILINX
The losses caused by low-level errors in purchasing chips may exceed your imagination. It may be production lag caused by pin mismatch, or direct losses on the production line caused by wrong parameters. Maybe you need to be more knowledgeable about the product to avoid this.It is necessary to be familiar with the naming rules of components. It will not only help you avoid purchasing wrong components, but also help you find alternative models. Engineers will also be more efficient and flexible in selecting models. Which parameters in naming can be flexibly replaced? The faster the xilinx component, the better the performance?
Naming rules of Xilinx Artix-7
• To understand this, let’s first look at a table to quickly learn the naming rules of xilinx.
• Xilinx Artix-7
Let’s go directly to the model number. If there is an extra L in front of the speed, it means low power. FG is the packaging technology type of the chip, G is ROHS environmental information, A is the package, 484 is the number of pins, C is the temperature grade, and there are several temperature grades of XILINX: C E I Q C is commercial grade 0℃-85℃.This naming rule table can analyze the naming rules of the four series of xilinx, including SPARTAN ARTIX KINTEX VIRTEX, which are these types of models. If you need the original picture of the table, you can send me a private message.
Which parameters in naming can be flexibly replaced?
Become familiar with the naming rules can we distinguish which parameters can be flexibly replaced.
• The first is that the speed level can be replaced, provided that the customer's design scheme is allowed. Generally speaking, speed represents the time from input to output of a device. If the processing process is faster, the better, use faster instead. is allowed.• Regarding temperature, xilinx provides four temperature ranges to choose from. In case of shortage and when the customer's product does not need to reach the extreme temperature, it can be flexibly replaced.
Which parameters in naming can be flexibly replaced?
The faster the chip, the better the performance and the more valuable it is. In fact, this is a misunderstanding.
• When buying chips, the most common thing is to buy the fast one. Is the faster the chip, the better the performance?. In fact, this is a misunderstanding. There is no one speed level for all devices. The exact definition, for Xilinx, the speed grade also has different meanings for FPGA and CPLD. 
• FPGA is actually the opposite. Every time you increase the number, the speed becomes about 5%. The larger the number, the faster the speed. Therefore, -5 is 10% faster than -4.
• This is the speed definition limited to xilinx, other brands define it according to the brand, so you still have to pay attention in the future.To make it easier for you to see, XILIN starts with CPLD.These models start with FPGA.
