Improved circuit behaviour modelling
Silicon Metrics has released multi-operating-point Synopsys Liberty Scalable Polynomial Delay Models (SPDMs) through its characterisation and modelling tools.
Silicon Metrics has announced the commercial availability of multi-operating-point Synopsys Liberty Scalable Polynomial Delay Models (SPDMs) through Silicon Metrics' characterisation and modelling tools While delivering both memory and performance improvements to existing Synopsys tool users, SPDMs provide for advanced multi-operating point analysis and will be required for future Synopsys products

Tools provide validation for complex SoC I/O
SiliconSmart IO is the industry's first commercial toolset designed to perform detailed characterisation, modelling and electrical specification compliance verification.
Signal integrity modelling spots fatal flaws
New from Silicon Metrics, SiliconSmart SI provides cell characterisation and modelling of signal integrity (SI), a critical requirement for complex SoC designs at 130nm and below.
Silicon Metricsū collaborative efforts with Synopsys, the technology leader for complex IC designs, have centred on bringing this new advanced modelling for nanometer design technology to mutual customers.
SPDMs are an advanced and flexible addition to Synopsys Liberty format, the open source industry standard for the specification of nanometer libraries.
SPDMs use polynomial equations to represent the response of a circuit as a complex function of input conditions, output load, rail voltages, and temperature.
Since cell response with respect to voltage and temperature can be highly nonlinear and interdependent, SPDMs represent circuit behavior more precisely than the linear scaling factors that many customer design flows rely upon today.
In addition, SPDMs are the foundation for Synopsys' future tool features such as multivoltage design, as well as other nanometer analysis capabilities.
Silicon Metrics' advanced characterisation infrastructure and new adaptive N-dimensional curve fitting algorithm produce highly accurate and efficient SPDM models.
Because the SiliconSmart CR reports the correlation of the curve fit and then validates the resulting models in Synopsys PrimeTime, the user can have confidence that the SPDM represents the characterisation data properly.
"Our long-standing relationship with Synopsys is key to the technology development of both companies", said Callan Carpenter, CEO of Silicon Metrics.
"Our commitment to our customers is to support important industry standards that enable state-of-the-art design flows.
Since multi-operating point SPDMs will be required for future Synopsys features and tools, we are happy to be first to market with a comprehensive 'generation through verification' flow for multi-operating point SPDMs".
Synopsys and Silicon Metrics stand ready to help customers and other EDA vendors adopt the SPDM standard.
