In the DA tool market, the relationship between EDA vendors and upstream vendors directly affects the market share of their tools in a certain market. In the high-end market of PCB design tools, Mentor Graphics and Cadence occupy the majority of the market, but in the field of computer motherboards, Mentor only has 10-20% of the market space. According to reports, this is mainly due to the closer cooperation between Cadence and upstream manufacturer Intel (the schematic reference design provided by Intel to downstream vendors is implemented by Cadence software), thus directly affecting the attitude of downstream manufacturers. In view of this, Mentor Graphics also strengthened its cooperation with Intel. According to Mentor Graphics technical engineer Yu Lifu, Mentor Graphics and Intel have reached an agreement, and Intel's future sets will be designed with Mentor Graphics tools. And these designs include not only schematic design, but also PCB design. "We believe that through the cooperation with Intel, Mentor's high-speed system design tools will greatly increase the market share of the computer motherboard market." Yu Lifu said.

"Our relationship with our customers is no longer a mere trading relationship, but a relationship between our partners and the community of interests, especially high-end tools, which is the result of a strong combination." Chen Lanbing, senior manager of the high-speed system technology center at Cadence, said. According to reports, Cadence's power integrity tool PI is jointly developed with SUN, and Cadence is working with Motorola to develop RFSiP package-level solutions.

With the development of technology and changes in the market environment, competition among manufacturers has shifted from supply chain, that is, cost competition to competition in the industry chain, that is, system manufacturers and chip manufacturers form a community of interests, and another system manufacturer and chip manufacturer. The competition between the interests of the community.
