Predictability/Reliability

Definitions

Predictability is the percent of designs in the last 12 months that taped out within +/- 2 weeks of the originally committed customer schedule.

Reliability is the percent of designs that had a defect requiring a respin due to an Open-Silicon or Open-Silicon IP partner design issue.

The Open-Silicon target for both predictability and reliability is 90%.

Impact on Market Share

Why is predictability so important?  It is well known that being late to market limits the share of market that can be gained:

In order to maximize the market share above, you need to both have silicon come out on time, and to work the first time.  One without the other offers clearly little value, which is why Open-Silicon has focused since inception on both parameters as the key metrics used to measure the effectiveness of our design organization.

Company Focus

Open-Silicon does not just precisely define and measure predictability and reliability.  We also report them to the board of directors at every board meeting and tie our executive compensation to it.  Design issues can arise from all parts of the organization, including design methodology, tools issues, customer design issues, IP, etc...  Only by focusing the entire team on these metrics can execution be ensured.
