Unfortunately, refining tools and flows requires incorporation of lessons learned, and this is true for almost every new process node. It's a real conundrum, because you don't want to be the first one to tape out a big SoC in the latest process, but time to market pressures don't give you much leeway to let others blaze the trail ahead of you.

That's so true! And some companies act like real drug addicts.

For current synthesis and analysis tools, they haven't addressed critical issues for nanotechnology For example, the product leakage is often 2X-4X higher than estimation because it is due to incorrect power model. The high design margin (20%-30%) in current SSTA is due to improper DFM setup, the actual margin can be reduced by half.

Chip design is one of the industries that rely heavily on the accuracy of tools for success. EDA is definitely very crucial.

Perhaps I could be even bolder and suggest that verification is much like the drug industry. Even if there were a cure, it is more profitable to sell things that work on the symptoms which keeps the customer coming back for more.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
