You might be surprised to find out how they really look at the open-source tools. Many of the proprietary tools are based on open source tools. For a really strong example of this, look at Spice. Based on my observations and private conversations, the big ones actually like us, and the little ones hate us. The big ones (Cadence, Synopsys) like us for several reasons. First, we fill a market that is unprofitable for them. We will always be in this market, never in their high profit market. We can potentially get people to use EDA tools early, with simpler tools, thereby increasing the market for their high profit tools. We provide competition for the companies that can threaten their business, without threatening them. They claim to support open standards, but sometimes can't deal with each other. We can be a neutral intermediary. We are not a threat to them, and they are not a threat to us. The well known low end ones (Electronic Workbench, Protel, Eagle) hate us, because they depend on the educational market for their feed, and we can provide benefit that they can't. Giving away crippled versions of their product, or cheap educational site licenses are key promotional tools. You find them on CD's in textbooks, and in college labs. We are their biggest threat, and they are our biggest threat. The startups build on open source, and will sing the praises of BSD license. The focus on some esoteric job and hope to make it big and sell out. Mostly their products are specialized enough that the work wouldn't be done without funding. We are not a threat to them, and they are not a threat to us. The real little guys are a diverse bunch. Some see us as a threat to them, but they are not a threat to us. Some see us a potential allies. They can provide some marketable value that hopefully will lead to profit, and they don't need to rely on potential competitors. We need to swing them over to our way. > In the event Mentor Graphics as donated their > format for usage without charge, I see no problems.

I don't know the official position, but based on some committee experience in the past, Mentor's behavior has not been open-source friendly. > Has anybody looked to see if IEEE or any other organization > has any official standards?

We need one that can be used by different types of tools. VHDL and Verilog are official standards. With the AMS extensions (also official standards) they provide much of what is needed for simulation and synthesis, both analog and digital. That's why I proposed building on VHDL. If we do this, and it works, industry will notice in a good way. They might even help us. There might be help available from both EDA vendors and EDA users. We can solve a problem that has been plaguing them for many years. The gschem and PCB formats are not elegant enough to be considered as standards. If somebody has a better idea, or knows of a better comprehensive standard, please tell me.
