1. What is FPGA chip?

FPGA is called Field-Programmable Gate Array. It is a on-site programming door array chip that can reconstruct the circuit to achieve different logical functions.It contains a large number of logical units, storage units and clock management circuits.Compared with fixed logic chips, FPGA has the characteristics of high flexibility and strong programming, and has been widely used in modern electronic systems.

2. How to choose a FPGA chip that suits you?

The selected FPGA chip needs to consider multiple factors in multiple aspects, including the number of logic doors, the ability of clock management, storage unit, communication interface, power consumption, price, manufacturing process, technical support, etc.Before selecting the FPGA chip, you need to understand your application requirements and the required chip specifications, and then compare the advantages and disadvantages of different chips to select.

3. Step 1: Determine application requirements

When selecting FPGA chips, you must first determine your application needs.For example, what logical functions do you need to implement, storage data volume, processing speed, power consumption requirements, and so on.With these needs, you can more clearly specify the technical indicators of the chip, such as the number of logic doors, the size of the storage unit, the type of communication interface, and so on.

4. Step 2: Choose the manufacturing process

The manufacturing process of modern FPGA chips is very complicated, and the advantages and disadvantages of each manufacturing process are different.Generally speaking, the smaller the craft node, the better the performance and power consumption of the chip, but the higher the price.When selecting the type, the progress and cost of manufacturing process need to be considered, as well as the balance between the performance and cost of your application.

5. Step 3: Consider power consumption and heat dissipation

Power consumption and heat dissipation are important factors that need attention when selecting FPGA chips.The power consumption is related to the number of logic doors, operating frequency, and use environment, while heat dissipation is related to chip packaging forms and heat dissipation design.When selecting the type, you need to consider the needs of power consumption and heat dissipation, and choose the appropriate chip and packaging form.


6. Step 4: Focus on the communication interface

The communication interface is the main way for the FPGA chip to interact with other devices, and it needs to be focused on the selection.Common communication interfaces include SPI, I2C, UART, PCIe, etc., and you need to select the corresponding interface type and quantity according to your application requirements.At the same time, it is necessary to consider factors such as interface levels and rates.

7. Step 5: Understand technical support

When choosing an FPGA chip, you need to consider the technical support of chip manufacturers.Good technical support can help you solve problems encountered in development and application and improve work efficiency.You need to know what technical support for chip manufacturers, such as technical documents, development tools, forums, training, etc.

8. Step 6: Consider price

The price of FPGA chip varies from manufacturers, models, quantities, etc., so it is necessary to comprehensively consider price factors when selection.At the same time, pay attention to the balance between chip prices and performance, and do not over -pursue performance and ignore cost control.


Step 7: Understand market dynamics

Understanding market dynamics can help you understand the development trends, technical directions, price trends, etc. of different chips.At the same time, you can also understand the market position and competitiveness of chip manufacturers to provide reference for selection.

10. Summary view

When selecting the FPGA chip, you need to fully understand your application needs and various technical indicators, and choose the chip model and manufacturer that suits your own.After weighing the advantages and disadvantages, a rational choice can ensure the stability and reliability of the chip in the application process.
