Mentor Graphics Deep Submicron Division Launches the Kronos Cell Characterization and Analysis Platform

Without correctly characterized libraries, an entire design project may be at risk, and designing at the wrong environmental corner or not taking advantage of a special operating voltage, may lead to slower, larger designs that waste power or take longer to close on timing.

Accurate Models
At 45nm and below, speed and power consumption are much more sensitive to environmental conditions including voltage and noise. Therefore, producing accurate models at the appropriate conditions is critical to achieving design success. The Kronos platform quickly generates accurate and complete timing/power models and incorporates unique methods for noise immunity and signal integrity to avoid design problems that otherwise might not be detected until failure analysis.

High Throughput
The Kronos Platform’s advanced algorithms and efficient job distribution reduces characterization time from weeks to days. During characterization, spice simulations are continuously monitored, and numerous data checks and recovery mechanisms significantly improve turn-around time by pinpointing specific model results and simulations if a problem is detected.

Kronos Characterizer
Kronos Characterizer is a high-throughput, general purpose cell library characterization tool for standard cells, complex cells, IO pad, and custom macros. The Kronos platform features high-performance integration with the best-in-class Eldo Classic SPICE simulator. Eldo Classic has been extensively optimized for cell characterization, offering quick simulation turnarounds and the industry’s most accurate results. The tight integration of Kronos Characterizer with Eldo Classic delivers improved performance for shorter total characterization time through dedicated features in the Eldo simulator that support library characterization.

Kronos Analyzer
Kronos Analyzer is a library analysis and verification tool for ensuring high quality libraries whether qualifying libraries from an external supplier or developing library models internally. The tool enables design engineers and library qualification teams to compare and validate complex ASIC cell libraries for design-critical characteristics such as performance, area, and power. Kronos Analyzer can be used with any cell characterization solution for library validation and optimization.

“Our customers know that sophisticated and robust Standard Cell Library analysis and characterization are of critical importance,” said Robert Hum, vice president and general manager, Deep Submicron Division (DSM), Mentor Graphics. “Our SPICE simulator, Eldo, has been optimized for cell characterization and used to drive this type of solution for many years. Now we have the opportunity to deeply integrate Eldo into a best-in-class characterization technology for optimal accuracy and performance.”
