Competition is good for every industry that I know of, so why would the competition between CCS and ECSM be bad for us? Let the marketplace vote with their dollars and we can settle which version is adopted.
Designers don't attend DAC because they are too busy using old tools to solve their present design. It's the exact same reason they don't have time to see time-saving new tool flows. Budgets are tight and DAC is seen as a fringe benefit.
I agree about opportunistic law firms that are not protecting a legitimate technology patent. I am also shocked at how much EDA intellectual property has been outright stolen, like the infamous Avant! case. Why didn't Jerry Hsu ever do prison time?
EDA software administration has increased in complexity based on direct demands from customers, plus from requirements by EDA companies to "keep honest customers honest" by enforcing contracts. I agree that installation should be as simple as any PC-based software where I merely click on the "Next" button and everything works.
You hit a big point on tool flows. It has been estimated that for every $1 spent on EDA tools that $4 is spent on integrating a working flow.
Mentor used to have a fairly monolithic system in the Falcon framework days, but guess what customers asked for? Standards-based, file-based, tool flows, not monolithic flows.
You failed to mention the common practice of EDA customers to wait until the final 10 days of the quarter to see which EDA vendor will cave-in and give them the best terms for their dollar, further driving down the Average Sales Price of tools. The line goes something like, "I"ve got a PO in my desk drawer for $1.2M and I want unlimited use of all your tools for 3 years. Do we have a deal? If not, your competitor is waiting in the lobby."
Driving the EDA ASPs downward has caused many EDA companies to have flat or declining revenues which leads to fewer resources to fix the issues that you have raised.
