Features

• Patented InsideView approach automatically pre-characterizes each cell using transistor-level circuit analysis to learn all internal logic states
• Enables automatic vector generation (AVG)
• Ensures a complete, accurate, and highly efficient characterization of library cells
• Supports complex cells including those required for high-speed and/or low-power design, such as pulse latches, multi-bit flip-flop arrays, level shifters, power switches, and cells with sleep modes
