Why use FPGA to verify the chip?

FPGA (programmable logic chip) is a flexible chip design technology. It can achieve different circuit functions through programmable logic units, which have the characteristics of reconstruction and programming.In the chip design and verification process, using FPGA can bring some important benefits.This article will explore the reason why the chip is verified by FPGA.

1. Improve test efficiency

FPGA can be tested on the actual chip, which can quickly simulate and verify the circuit function of the chip, thereby improving the efficiency of testing.At the same time, the configuration of the test can be adjusted by modifying the programming code of the FPGA, increasing the test coverage, and increasing the accuracy and effect of the test.

2. Ensure the correctness of the circuit function

The key to chip design is to ensure the correctness of the circuit function.The use of FPGA can ensure that the function of the chip circuit is correct, and verification before chip production can be made to avoid problems with chip after production.Especially for high -performance chips, FPGA can effectively verify the design of the chip to ensure that its performance reaches the expected level.

3. Reduce production cost

The use of FPGA verification circuit functions before chip production can find problems in targeted, reduce debugging in the production process, thereby reducing production costs.In addition, the use of FPGA can also reduce the time and cost of hardware development, because hardware development is an expensive job.

4. Simplify system development

Using FPGA for chip verification can help simplify the system development process.Through FPGA prototype test, the prototype development of the hardware system can be quickly completed and the system development process can be accelerated.In addition, FPGA can also easily connect various peripherals for system development and testing.

5. Improve team efficiency

Using FPGA for verification can improve the work efficiency of the team.Designers can quickly modify the code of FPGA and perform corresponding tests in order to verify whether the circuit function is correct.This process can be iterated quickly and complete design and testing.

6. Support multiple chip design

FPGA’s programmable logic unit and reconstructor enable it to support multiple chip design.Use FPGA to verify that different types of chip design can be tested in targeted manifestations, including digital circuits, analog circuits, communication and signal processing chips.

7. Realize fast prototype development

The use of FPGA can help achieve fast prototype development.Using FPGA for prototype testing, developers can quickly simulate and verify the circuit function of the chip, so as to quickly iterate in the development process and reduce the development cycle and cost.

8. Convenient for subsequent maintenance

After the production of chips, using FPGA to test the chip can ensure the integrity and correctness of the chip.This is very important for subsequent maintenance, because the problem after chip production often needs to modify the chip, and the use of FPGA for chip verification can quickly and accurately find out the problem and modify it.

9. Support different development platforms

FPGA can support different development platforms, including programming languages such as VHDL and Verilog.This means that different developers can choose their familiar platforms for development.In addition, FPGA can also support different development tools and development environments, which facilitates the cooperation of the development team.

10. Support the reuse of the design scheme

Using FPGA for verification can support the reuse of the design scheme.Although each chip is unique, some design schemes can be shared and reused in different chip design.After using FPGA to verify the design scheme, the verified scheme can be copied into other chip design, thereby saving development time and cost.

In general, using FPGA for chip verification can improve test efficiency, ensure the correctness of the circuit function, reduce production costs, simplify system development, improve team efficiency, support different chip design, realize fast prototype development, facilitate subsequent maintenance and support design solutionsReuse.All these advantages make FPGA an important tool for chip design and verification.
