  • Publication number: 20250131171
    Abstract: Embodiments herein describe techniques for identifying excess antennas (or antenna diodes) in a IC design using computer software tools. An IC design can be changed for any number of reasons, which can change the number of antennas that are required to sufficiently protect the IC from damage during the fabrication process. Currently, a chip designer would use a ratio to determine whether a portion of the IC (e.g., a macro) has too many or too few antennas. The embodiments herein describe techniques where computer software tools identify excess antennas for the designer. The designer can then decide whether to remove these antennas. In another embodiment, the computer software tools may automatically remove some or all of the identified excess antennas, without input from the chip designer.

  • Patent number: 12001774
    Abstract: A method for curing antenna violations on an integrated circuit that includes multiple levels includes: obtaining a design of a circuit, the design including a first element connected to first device and a second element connected to one or more second devices, wherein the first and second elements both receive a common signal; determining that an antenna violation exists in on the first element at a first level of the multiple levels; and modifying the design of the circuit to add a connected between the first element and the second element at the first layer or at a layer below the first layer.

  • Patent number: 11526651
    Abstract: Embodiments of the invention include protecting against antenna violations in a macro having a clock mesh. Aspects include obtaining a design of the macro, the design including a clock layer having a plurality of clock pins and determining a longest vertical wire and a longest horizontal wire allowed based on a design of the clock mesh. Aspects also include identifying, based at least in part on the longest vertical wire and the longest horizontal wire, a plurality of checkbox regions for a clock pin of the plurality of clock pins and calculating a total diffusion area for each of the plurality of checkbox regions. Aspects further include adding, to the design of the macro, an antenna diode to the clock pin based on a determination that the total diffusion area for any of the plurality of checkbox regions is less than a threshold value.

  • Patent number: 8213414
    Abstract: The subject matter described herein includes methods, systems, and computer program products for providing TDM terminating services in a packet network. According to one method, a combined set including a plurality of TDM channels is received over a packet network. The combined set of TDM channels is terminated in the packet network as a combined TDM facility. Terminating the TDM channels as a combined TDM facility may include providing at least one terminating TDM service for the TDM channels, such as performing CAS signaling or providing a PRI interface for the TDM channels.

  • Patent number: 7982768
    Abstract: A driver-assisting apparatus includes a video camera and a display. The video camera is attached to a vehicle for taking pictures in a field further than a driver's field of view with bare eyes. The display is connected with the camera for displaying the pictures. With the driver-assisting apparatus, the driver can see an object that is too far for her or him to see with the bare eyes. Thus, the driver can take actions to avoid running over or bumping into the object earlier with the driver-assisting apparatus than without.

  • Patent number: 7940772
    Abstract: The subject matter described herein includes methods, systems, and computer program products for transporting ATM cells in a device having an Ethernet switching fabric. According to one method, at least one ingress ATM cell is received at an ATM network interface of a device having an Ethernet switching fabric. Next, the connection associated with which the ingress ATM cell is identified. The ATM cell is encapsulated in Ethernet frame addressed to a media processing resource associated with the connection. The Ethernet frame is forwarded to the media processing resource across an Ethernet switching fabric.

  • Patent number: 7774625
    Abstract: Adaptive voltage control. In accordance with a first embodiment of the present invention, a desirable operating frequency for the microprocessor is determined. Information stored within and specific to the microprocessor is accessed. The information can comprise coefficients of a quadratic approximation of a frequency-voltage characteristic of the microprocessor. An efficient voltage for operating the microprocessor at said desirable operating frequency is computed. The microprocessor is operated at the efficient voltage.

  • Publication number: 20080034038
    Abstract: Contents such as a GUI or application output can be shared in a chat environment. The user can choose to share own contents or request that contents be shared by another user (e.g., a chat partner). It can be possible to control the shared GUI or application from the recipient's location. The shared content can be integrated in content that is transmitted as part of a chat session.
