Based on a unique Nangate patented technique Nangate Design Optimizer is capable of creating an optimized gate-level design with area, speed or power benefits as a result.
The latest product addition is an important milestone in Nangate's mission to provide digital IC designers with the benefits of full custom design implementations while preserving the advantages of cell-based design methodologies.
"With today's nanoscale manufacturing technologies, Nangate Design Optimizer delivers on an idea whose time has come," says Ole Christian Andersen, CEO of Nangate.
"It is a well-known fact that high pin-count gates and reduced number of logic levels in carefully designed complex cells have a dramatic influence on key design metrics. The increasing dominance of wire delays and interconnects makes the introduction of complex cells and application-specific libraries even more compelling for the advanced process nodes.
"The problem to date has been that commercially available physical synthesis tools and libraries have gravitated towards a preference for low complexity cells. Consequently, most physical synthesis flows are simply not able to fully utilize the existence of complex gates in a given library. Creation of a "richer" library is not always enough to enhance design performance. The synthesis mapping process and generation of bespoke cells are essentially interdependent disciplines that require close integration of tools in order to get optimal results", he continues.
Nangate Design Optimizer complements physical synthesis flows from Synopsys, Cadence and Magma by use of mapped Verilog(R) netlists and enables the following three modes of operation at increasing levels of optimization:
-- Design optimization with an existing std. cell library - Nangate Design Optimizer is capable of improving the original structural mapping to include more complex cells already present in the library. This alone often yields considerable design gains.
-- Design optimization by augmenting additional cells to the library - Nangate Design Optimizer can specify additional bespoke cells for the library and include these in the design which can provide even greater design benefits.
-- Design optimization with a new library - For optimum results, Nangate Design Optimizer can specify the 'ideal' library for the specific design including cell design parameters such as row height, cell functions, transistor sizing strategy, drive strength variants, etc.
The product is currently released for field testing through beta programs with a number of select customers. General availability is expected by third quarter this year.
Nangate Design Optimizer is fully compatible with other Nangate solutions including Nangate Library Creator and Nangate Library Characterizer which together provide a total solution that allows optimal library generation to become an integral part of the physical design flow.
Nangate develops and markets Electronic Design Automation tools and intellectual property that allow customers to take full advantage of current and next-generation IC technologies. The company provides a unique alternative to one-size-fits-all standard-cell libraries and a low-risk alternative to custom library development or full-custom chip design. Nangate software provides a complete environment to optimize designs for maximum performance and yield while minimizing power consumption, area, and time to market.
