Comparison & Validation

Library analysis and validation is critical, whether users are qualifying libraries from an external supplier or developing their own internally. With over 1 million data points per library, manual analysis and validation is not feasible. Kronos Analyzer enables design engineers and library qualification teams to compare and validate complex cell libraries for design-critical characteristics such as performance, area, and power. Early validation saves time and results in higher performing, more efficient designs with better correlation to silicon.

Evaluation & Qualification

Qualification Flow

Before a design begins, a library qualification team must decide on the foundry, library vendor, technology, feature size, and library version. There are both macro issues—such as process availability, yield, and corporate relationships—and critical performance issues to consider. Kronos Analyzer lets library qualification teams make well informed decisions by providing quantitative data as well as a graphical representation of the differences between libraries.

Kronos Analyzer’s unique matching technology enables the library qualification team to quickly evaluate libraries across a wide range of operating conditions without the long delays of running hundreds of full chip design flows.

Analysis & Validation

Validation Flow

Design engineers can use Kronos Analyzer to learn how process changes will affect their libraries and how changes in the libraries will influence their designs. Evaluating the effects of a process change on setup and hold times for an existing design, for example, can quickly determine what additional required sign-off checks.

Designers also evaluate libraries across operating conditions and special signoff corners to determine how components track across process-voltage-temperature (PVT). This information is essential in improving the risk/reward tradeoff for setting margins and operating conditions. Library developers tune existing components and compare new cells against existing ones to learn if changes have the expected effect. Kronos Analyzer also provides quality assurance, checking to see that new library releases do not have any unexpected characteristics.
