An exemplary method for simulating the effect of mismatch in design flows comprises receiving measured data, receiving an original model, extracting a mismatch model based on the measured data and the original model, attaching the mismatch model to the netlist to obtain a modified netlist, and simulating an effect of mismatch based on the modified netlist. In one embodiment, the extracting of a mismatch model includes selecting a set of model parameters, generating a distribution of mismatch values for each of the model parameters, extracting a set of linking coefficients based on said mismatch values, and extracting said mismatch model based on said set of linking coefficients. In another embodiment, the attaching of the mismatch model to the netlist includes determining a number of layers in the netlist, generating a copy of a lower layer in the netlist, the copy including a reference to a mismatch model definition, generating a copy of a higher layer in the netlist, replacing a reference to the lower layer in the higher layer by a reference to the copy of the lower layer, and generating a new model definition.

A system and method of simulating operation of an integrated circuit. First, circuit characteristics of circuit components are measured, and a set of circuit simulation model parameters are generated for each measured circuit component. Then, the operation of predefined circuit primitives is simulated using each of the generated sets of circuit simulation model parameters. The circuit primitives include the measured circuit components. The simulated operations are then analyzed to select ones of the simulated operations that are worst, best and nominal with respect to a specified circuit performance parameter and to extract model parameters corresponding to the worst case, best case and nominal case sets of circuit simulation model parameters from the generated sets of circuit simulation model parameters. Each extracted set of circuit simulation model parameters comprises one of the generated sets of circuit simulation model parameters. Then a target circuit is simulated using each of the worst case, best case and nominal case sets of circuit simulation model parameters so as to generate data representing the target circuits under worst case, best case and nominal case manufacturing conditions.

The invention relates to a method for associating a client with an access point using a security protocol. The method may include initiating a handshake and exchanging operational information between the access point and the client, establishing an encrypted operational key if the operational information is validated and entering an operational phase using the operational key and an unique service set identifier if valid.
摘要:
Techniques and systems for associating a client with an access point using a security protocol are described. A described technique includes initiating an association request; establishing an association between a first device and a second device different from the first device based on the association request; participating in a handshake including exchanging an operational key between the first device and the second device during the handshake; and entering an operational phase using the operational key when the handshake is successful. Participating in the handshake can include participating in an authenticated handshake when the association request indicates an authenticated access, and participating in an unauthenticated handshake when the association request indicates an unauthenticated access.
