It’s rare in EDA to see competitors agreeing, but an interesting article in EEtimes Europe this week caught my eye, by Lauro Rizzatti the VP Mktg of EVE. Lauro discussed a survey EVE ran during DAC, where they asked customers how they felt about the current state of hardware-assisted verification, what their priorities were, etc.
One paragraph really stood out (emphasis mine): “More interesting was the ranking of six criteria in selecting the next hardware-assisted verification platform, including run-time performance, compilation performance, visibility into the design, in-circuit emulation (ICE), four-state support and price. Visibility into the design and compilation performance scored high, but run-time performance and price finished close behind.”
How ironic that he was naming exactly those criteria where Palladium has competed for years and consistently won! I could dive into a lecture on the strengths of Palladium, but I won’t (you can see the marketing literature here http://www.cadence.com/products/sd/palladium_series/pages/default.aspx). But, I want to say there were two major criteria missing from Lauro’s survey that are arguably more important than any of the six he mentioned. The first is flexiblity/scalability. Whenever I talk to customers about to make a major investment in hardware-assisted verification, the key question everybody asks is “How can I maximally leverage this?”. To maximize leverage from one’s investment in hardware assisted verification one needs:
The second key criterion is what many people call “debug loop time” (for lack of a better word, it’s the time required to find/fix a bug and resume whatever you were doing). This is actually more important than runtime performance per se; besides visibility into the design, controllability of the debug/runtime environment is also critical.
The EVE/Lauro Rizzati article mentioned neither of these two criteria. Maybe is it because FPGA-based architectures are known to have issues with these from time to time? (Palladium’s architecture is processor-based.)
However, I think EVE neglecting to mention these other factors was too self-serving. Customers deserve a balanced picture. Ultimately what customers really care about is: “How fast can I verify my current and future SoCs to a desired level of confidence” and “How much will it cost me now and in the future”?
Every customer has different needs. Some solutions are a better “fit” than others. Unfortunately, Consumer Reports doesn’t evaluate EDA tools (yet), so I would urge customers to do their homework and evaluate carefully.
