Abstract :
The coupling of signals between sensitive nets by signals from digital and large-swing analog nets and effects of unwanted parasitic capacitances due to overlapping nets are a concern in the design of analogue VLSI circuits. A two-layer, detailed channel-routing algorithm for mixed analog and digital signal nets has been developed to address these problems. The algorithm accounts for capacitive coupling between nets on the same layer and on adjacent layers. It has been implemented in the C programming language
