market share
Xilinx and Altera are the two largest manufacturers in the FPGA market. Xilinx occupies about 50% market share in FPGA market, and Altera occupies about 30% market share. Other FPGA vendors have a relatively small market share, but they have performed well in specific fields.
technical superiority
The technical advantages among FPGA manufacturers are mainly reflected in the performance, power consumption, cost and reliability of FPGA chips. Xilinx and Altera have their own advantages in these aspects. For example, Xilinx's FPGA chip usually has higher performance, while Altera's FPGA chip usually has lower power consumption. In addition, FPGA manufacturers are constantly introducing new technologies to improve the performance and power consumption of FPGA chips.
Product characteristics
The product characteristics of FPGA manufacturers include the scale and speed of FPGA chips, as well as supporting development tools and software. The FPGA chips of Xilinx and Altera are usually larger than those of other manufacturers, so more complex digital circuits can be realized. In addition, Xilinx and Altera both provide rich development tools and software to help users develop and deploy FPGA applications more easily.
operation sequence/order
If you want to use FPGA chip to realize digital circuit, you can follow the following steps:
1. Choose a suitable FPGA chip and consider its scale, speed, power consumption and cost.
2. Choose a development tool and software, such as Vivado of Xilinx or QuartusPrime of Altera.
3. Use development tools and software to design and verify digital circuits.
4. Download the designed digital circuit to the FPGA chip.
5. Test and debug the FPGA application to ensure its performance and reliability.
