Abstract: A user is presented with a simulation environment within which the user is provided a choice to select between parasitic simulation modes of varying accuracy, the modes including a mode without parasitics and a plurality of modes including parasitics with a varying degree of accuracy. A selection from among the modes is received from the user and simulation test are performed at the selected degree of accuracy.

Abstract: Techniques are presented for accounting for parasitics in the automated design of integrated circuits. In one set of techniques, model values for parasitic models are received on a schematic environment from a user, the parasitic models are evaluated from the schematic using the received model values, the parasitic models are transferred to a layout environment, and the transferred parasitic models are evaluated on the layout environment. In other techniques, model values are received for parasitic models from a user, the parasitic models are evaluated on the layout environment, and the process then backannotates the parasitic models evaluated on the layout environment and corresponding parameter values to a schematic environment.

Abstract: The present invention relates to a method and system for tuning a circuit. In one embodiment, the method includes receiving a description of the circuit, and selecting a design point of the circuit for evaluation using a sizing tool, where the design point comprises a design of the circuit that meets a set of predefined design specifications, and the circuit comprises a group of circuit devices. The method further includes receiving a set of tuning information for the group of circuit devices tuning the group of circuit devices using the set of tuning information to create a group of tuned circuit devices, creating an updated layout of the group of tuned circuit devices using a layout tool, creating estimated parasitic information of the group of tuned circuit devices using the updated layout, and verifying the design point meets design goals of the circuit using the estimated parasitic information of the updated layout.
