This PyCell creates a differential pair with a wide range of options. Users may specify fingers for interdigitation and stack multiple rows of fingers. Additional parameters are available for modifying contact-to-gate spacing, diffusion width, wire width, guard rings and dummies. The connectivity, spacing and contacts conform to the design rules for the process in use.
This PyCell creates connectivity between fingers, but leaves row connectivity to the user for maximum flexibility. The object-oriented architecture of the Ciranova Layout API handles the complex wiring requirements of multiple fingers. Each finger is treated as an object that is connected by passing a numeric sequence as a method to do the actual wiring.
