The GSS Tool Chain

Download flyer.

The GSS tool chain is illustrate below. It contains the 3D statistical atomistic GARAND, the statistical compact model extractor Mystic and the statistical circuit simulation engine RandomSpice. Additional modules focused on statistical SRAM simulation and standard cell characterisation are in the process of development.

A common database architecture allows the seamless flow of data between the tools in the GSS tool chain. The efficiency and productivity of the GSS tool chain is enabled by the use of a fully automated cluster job submission and management system that allow simultaneous execution of thousands of statistical device simulations, compact model extractions and circuit simulation tasks on clusters with a large number of processors. The job submission and management is interfaced to the GSS database, automatically harvesting and annotating the results of statistical device simulation, compact model extraction and circuit simulation.
