摘要: This paper describes EXCL, an automated circuit extraction program that transforms IC layout into a representation suitable for detailed simulation. The has built-in, general algorithms capable of accurate computations interconnection resistance, internodal capacitance, ground and transistor sizes. However, where possible, the are replaced with simple techniques, thereby improving execution speed. A basic component extractor is procedure decomposes regions domains appropriate specialized or algorithms. decomposition algorithm, discusses how they connect rest EXCL.
