SAN FRANCISCOBeleaguered EDA vendor Cadence Design Systems Inc. has removed a number of companies from membership in its Connections program, a collaborative effort to support software suppliers offering complementary tools.
The action was first brought to light Nov. 20 in an anonymous letter posted on EDA users' site Deepchip.com.
According to the anonymous letter, a total of 48 companies are believed to have been removed from Connections, including Mentor Graphics Corp. and Magma Design Automation Inc., the third- and fourth-ranked EDA vendors by revenue.
Cadence, which is closed this week, did not immediately respond to requests for comment. There are still more than 125 member companies in the Cadence Connections program, according to the Connections web site.
Yatin Trivedi, Magma's director of industry partner programs, said he had not been contacted directly by Cadence about Magma's status in the Connections program, but noted that Magma is no longer listed as a member on the program's Web site.
While companies are free to decide who they will partner with and for what reasons, Trivedi said Cadence closing the door on so many companies would be detrimental to the EDA industry and customers, nearly all of whom buy design tools from multiple vendors and need them to work together.
"A large company like Cadence should not be stooping down to this level," Trivedi said.
Lauro Rizzatti, general manager of EVE-USA, confirmed that his company was among those whose membership in the program was not renewed. Rizzatti said EVE has been a member of the program since 2002 and was told as recently as August that its membership, which expired in October, would be renewed.
But just days before the membership was set to expire, Rizzatti said EVE received a very dry phone call from Cadence informing the company that its membership would not be renewed and that Cadence did not see any value in continuing the relationship.
Originally, Rizzatti assumed that the decision was related to the fact that Cadence and EVE are competitors in the area of emulation and the fact that Cadence is undergoing a management transition. Perhaps the company's interim leaders did not want to continue cooperating with companies that it competes with in some areas, he thought.
But when Rizzatti saw the list published on Deepchip.com he was surprised to see so many companies had apparently suffered the same fate.
Rizzatti expects being removed from the program will cause problems for EVE and for mutual customers of the two companies. EVE will not be able to guarantee that its emulator will work with Cadence products without the access that being part of the Connections program provided, he said.
Rizzatti could not attest to the accuracy of the 48 companies listed in the anonymous letter, but said he has personal knowledge of at least three companies being removed, including EVE.
