An integrated system includes a system user interface (SUI) that provides an iconic, at-a-glance representation of integrated security system status. The SUI is for use across all client devices including mobile or cellular telephones, a mobile portal, a web portal, and a touchscreen device. The SUI includes a number of display elements presented across all types of client devices for monitoring status of the integrated security system. The display elements of the SUI include an orb icon, text summary, security button, device warnings, system warnings, interesting sensors, and quiet sensors. The SUI thus provides system status summary information agnostically across all clients. Additionally, the SUI provides consistent iconography, terminology, and display rules across all clients as well as consistent sensor and system detail across clients.

Cross-client sensor user interface in an integrated security network

An integrated security system is described that integrates broadband and mobile access and control with conventional security systems and premise devices to provide a tri-mode security network (broadband, cellular/GSM, POTS access) that enables users to remotely stay connected to their premises. The integrated security system, while delivering remote premise monitoring and control functionality to conventional monitored premise protection, complements existing premise protection equipment. The integrated security system integrates into the premise network and couples wirelessly with the conventional security panel, enabling broadband access to premise security systems. Automation devices (cameras, lamp modules, thermostats, etc.) can be added, enabling users to remotely see live video and/or pictures and control home devices via their personal web portal or webpage, mobile phone, and/or other remote client device. Users can also receive notifications via email or text message when happenings occur, or do not occur, in their home.

Embodiments include systems and methods comprising a gateway located at a premise forming at least one network on the premise that includes a plurality of premise devices. A sensor user interface (SUI) is coupled to the gateway and presented to a user via a remote device. The SUI includes at least one display element. The at least one display element includes a floor plan display that represents at least one floor of the premise. The floor plan display visually and separately indicates a location and a current state of each premise device of the plurality of premise devices.

Static timing and/or noise analysis are performed on a netlist of an integrated circuit, to estimate behavior of the netlist and to identify at least one violation by said behavior of a corresponding requirement thereon, such as setup time, hold time or bump height in a quiescent net. Thereafter, effect of engineering change order (ECO) to correct the violation are automatically analyzed, based on the layout, the parasitics, the timing and/or noise behavior, and the violation, followed by generation of a constraint on the behavior (called “ECO” constraint), such as a timing constraint and/or a noise constraint. Next, the ECO constraint is automatically used, e.g. in a place and route tool, to select an ECO repair technique, from several ECO repair techniques that can overcome the violation. The selected ECO repair technique is automatically applied to the layout, to generate a modified layout which does not have the violation.

A computer-implemented method of determining an attribute of a circuit includes using a computationally expensive technique to simulate the attribute (such as timing delay or slew) of a portion of the circuit, at predetermined values of various parameters (eg nominal values of channel length or metal width), to obtain at least a first value of the attribute The method also uses a computationally inexpensive technique to estimate the same attribute, thereby to obtain at least a second value which is less accurate than the first value Then the computationally inexpensive technique is repeatedly used on other values of the parameter(s), to obtain a number of additional second values of the attribute Applying to the additional second values, a function obtained by calibrating the at least one second value to the at least one first value, can yield calibrated estimates very quickly, which represent the attribute's variation relatively accurately

Determining a design attribute by estimation and by calibration of estimated value

An equivalent waveform for a distorted waveform used in timing and signal integrity analysis in the design of an integrated circuit is automatically generated. The equivalent waveform is produced by calculating the transition quantity of a first non-distorted waveform. The transition quantity is the amount of transition of the first non-distorted waveform that is required for the cell to produce an output waveform with a predetermined end voltage. The end point of the transition period for the distorted waveform is then determined based on when the distorted waveform has accumulated the same transition quantity. The equivalent waveform can then be formed by computing a second non-distorted waveform such that the end point of the transition period for the second non-distorted waveform coincides with the end point of the transition period for the distorted waveform.

Determining equivalent waveforms for distorted waveforms

Noise glitches can cause timing degradation in switching nodes or incorrect transitions in steady-state or "quiet" nodes. These incorrect transitions can propagate through the circuit, and can create functional errors or failures. This paper presents both a method and a practical implementation technique for accurately and efficiently characterizing and modeling the propagation of noise glitches through a cell within an integrated circuit. A characterization methodology is developed to generate noise immunity criteria (NIC) and noise propagation tables (NPT) for a given cell library. The resulting look-up tables are appended to any standard gate-level library to be utilized by static timing and noise analysis (STNA) tools.

Noise library characterization for large capacity static noise analysis tools

Noise glitches can cause functional errors or failures if they are latched into sequential cells. Thus it is very important to determine or characterize noise failure criteria of sequential cells. However, characterizing noise failure criteria of sequential cells is very computationally expensive because it often requires multiple transient simulations with different clock waveform shapes and alignments, known as clock sweeping. In this paper, we propose a new technique that eliminates the clock sweeping by using the meta-stable point of sequential cells. Our experiments with industrial circuits have shown that the proposed method is on average 58/spl times/ faster than the conventional clock sweeping method and its average error is only 2.4%.
