si2 silicon integration initiative

Statistical approach to the design of integrated microcircuits which was discussed several years ago, was ready to become accessible in mass. In any case, the corporation altos design automation is ready to grant the statistical library variety for the standardization within the initiative si2 (Silicon integration initiative). In the past year company also released Liberate, tool traditional, static analysis.
The statistical analysis of the pulses propagation time which considers the changeability of technological process and which makes possible to estimate statistical distribution, becomes very important for the standards of 65 nm and less. However, one of the problems is the absence of accessible characteristic statistical libraries and the absence of the standard format libraries. This problem si2 plans to solve by the start of developers in coalition OMC (Open modeling coalition). On the assertion Of altos, its technology makes possible to accelerate the process for the characterization of libraries by an order, thus for the generation of statistical model it is required as much time as is required for creating the static model.

This notes is sufficiently daring assertion (and with it they are not agreeable into Magma, asserting that their tool siliconSmart is more rapid), since with the creation of statistical model it is necessary to consider variations in the set of parameters, in particular each transistor in the cell. Therefore frequently for the creation of the statistical model departs from 20 to 50 more time, than usual. If the standardization Of variety within the OMC passes successfully, Altos will obtain significant advantage, since now company is forced to work individually with vendor by EDA- tools, ensuring the compatability of its libraries with their products. In particular, Altos collaborates with Cadence, Extreme DA and Magma design automation, which develop their own statistical libraries, and they are also terms OMC.

As explained Altos, the key special feature Of liberate and Variety that makes possible to generate models to ten times faster than the analogous libraries of competitors, appears the technology internal view , that none other preliminary analysis integrated in the circuits. But if we compare Variety from Liberate, then if necessary the characterization of three systematic (for example, the length of channel, thickness of the oxide layer and even any parameter of technical process) and one random (threshold stress) the parameters, then the time of operation with the first will be six times more than the latter.
