A system for virtual control of electronic laboratory equipment includes a local computer system. One or more items of electronic laboratory equipment are connected to the local computer system. Each item of electronic laboratory equipment has a physical control panel including one or more displays or controls. A virtual control panel generation unit generates a virtual control panel accessible from a remote computer system. The virtual control panel is substantially similar to the physical control panel in appearance. A command interpretation unit monitors interaction between the remote user and the virtual control panel and generates electronic laboratory equipment commands for exploiting the functionality of the electronic laboratory equipment.

An emission map of a circuit to be tested for alterations is obtained by measuring the physical circuit to be tested. An emission map of a reference circuit is obtained by measuring a physical reference circuit or by simulating the emissions expected from the reference circuit. The emission map of the circuit to be tested is compared with the emission map of the reference circuit, to determine presence of alterations in the circuit to be tested, as compared to the reference circuit.

A Scanning Time-Resolved Emission (S-TRE) microscope or system includes an optical system configured to collect light from emissions of light generated by a device under test (DUT). A scanning system is configured to permit the emissions of light to be collected from positions across the DUT in accordance with a scan pattern. A timing photodetector is configured to detect a single photon or photons of the emissions of light from the particular positions across the DUT such that the emissions of light are correlated to the positions to create a time-dependent map of the emissions of light across the DUT.

A background process is used to install at least one system hook for message interception of integrated circuit chip layout display software. A call message is intercepted through the system hook, and, responsive to the call message, current layout coordinates are read from the integrated circuit chip layout display software. A representation of the current layout coordinates is entered into tool control software configured to control a physical tool for analyzing integrated circuits, and the physical tool is controlled with the tool control software, based on the representation of the current layout coordinates. In an “inverse” approach, a background process is used to install at least one system hook for message interception of tool control software configured to control a physical tool for analyzing integrated circuits, and a call message is intercepted through the system hook. Responsive to the call message, current coordinates are read from the tool control software. A representation of the current coordinates is entered into integrated circuit chip layout display software, and at least a portion of an integrated circuit layout, corresponding to the representation of the current coordinates from the tool control software, is displayed.

Improved process variation sensors and techniques are disclosed, wherein both global and local variations associated with transistors on an integrated circuit can be monitored. For example, respective circuits for sensing a global process variation, a local process variation between neighboring negative-channel type transistors, and a local process variation between neighboring positive-channel type transistors are disclosed. Further, in one example, a method for sensing a process variation associated with transistors on an integrated circuit includes providing at least one process variation sensor on the integrated circuit, the process variation sensor comprising a sensing portion including one or more transistors and a loading and amplification portion including one or more transistors, and operating the one or more transistors of the sensing portion and the one or more transistors of the loading and amplification portion in a subthreshold region of transistor operation such that when a threshold voltage of at least one of the transistors changes, a process variation is sensed.

This embodiment replaces the use of LBIST to get a pass or no-pass result. A selective signature feature is used to collect the top failing paths, by shmooing the chip over a cycle time. These paths can be stored on-chip or off-chip, for later use. Once the chip is running in the field for a certain time, the same procedure is performed to collect the top failing paths, and this is compared with the stored old paths. If the order of the top paths changes, it indicates that (for example) there is a path (not the slowest path before) that slows more than others, which could be potential reliability concern. Therefore, a potential reliability failure is identified in the field.

Light-controlled circuit characterization techniques are disclosed. For example, a technique for testing an integrated circuit includes the following steps/operations. At least a portion of the integrated circuit is stimulated with a light source so as to affect one or more electrical characteristics associated with the integrated circuit. By way of example, the light source may be a laser. Optical emissions are captured from the portion of the integrated circuit stimulated by the light source and/or one or more portions of the integrated circuit associated with the stimulated portion. The optical emissions are associated with one or more switching operations of one or more components of the integrated circuit. At least a portion of the captured optical emissions are processed to provide information about the integrated circuit.
