Mentor Graphics Corp. has expanded its Kronos Cell Characterisation and Analysis platform to include embedded memories. According to the company, the platform quickly produces accurate performance models for standard cells, I/Os, complex cells and embedded memories within an advanced, integrated environment.

Characterisation and analysis of embedded memories poses unique challenges: large circuit size can lead to excessive runtime, complex internal circuitry and a variety of choices available for pin-bus models requires a high level of automation. The Kronos platform addresses these challenges with proven, integrated capabilities, the firm noted.

In managing the characterisation and analysis of embedded memories, the Kronos platform delivers ease of configuration that enables an automatic characterisation flow, said the company. The automated flow runs netlist reduction, all simulations and creates complete .libs. The flow employs fast simulation techniques and precise circuit setup and measurement controls.

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.

The Kronos Platform's advanced algorithms and efficient job distribution reduces characterisation time from weeks to days. During characterisation, 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. The Kronos technology is tightly integrated to the Mentor Eldo SPICE simulator providing three times performance improvement over loose, API type simulator integrations, added Mentor Graphics.
