    This paper discusses the method to enable the programmability of I/O drive strength in Structured ASIC by maximizing reuse of existing DFT and OCT calibration block circuit with minimum logic added. The procedures and mechanisms of I/O programmability in structured ASIC are outlined in this paper.

    Volatile data storage is often backed by a battery. Its contents become the key used to decrypt incoming encrypted data. Without write protection this volatile data is subject to corruption during any of the following situations: chip power-up, chip power-down, and chip disconnection from its primary power supplies....

    To boost the output level of the TX buffer to compensate the loss through a lossy environment for these applications (repeater, re-buffering stage), a pre-emphasis digital filter stage is added into the reverse-serial loopback path.

    FPGAs by definition are programmable devices that can be configured in a multitude of ways that allows FPGA consumers to implement many different kinds of solutions. There are many advantages of this type of platform, one of which is the ability to reprogram the device after its initial programming. One use of this...

    New high speed devices in BGA packages are sensitive to small changes in voltage on the power supply pins and any voltage drops because of contact resistance between the package ball and the test interface. 4-point crown pogo pins are captured in plastic for the test interface. One of the causes of higher contact...

    Dedicated LVDS output buffer is supported. Many I/O standards are unterminated and are required to support long durations of AC undershoot or overshoot voltage. The new circuit addresses long periods of undershoot which may affect the functionality of the I/O.

    Devices use 2.5V IO devices to implement their output drivers. HCI causes significant Idsat reduction over the life of these devices when operated at a voltage of 3.3V instead of 2.5V. Figure 1 below shows a block diagram of the output driver’s pulldown. The 8x, 4x, etc.. gives the relative resistance of each of...

    Fast edge rates are a major contributing factor to high SSO. By reducing signal edge rates at the pad, SSO is reduced for two reasons: 1.Slower edge rates reduce the noise due to mutual coupling caused by adjacent aggressors. 2.Slower edge rates reduce the peak current required per transition, which help the overall...

    A max VCCIO of 3.45V, but uses a transistor technology in I/O buffers. As a result, it is important to limit AC overshoot/undershoot at I/O pins.

    Instance objects are derived from object definitions. Persistent objects are defined as instance objects that will be saved so that they can be reused over the lifetime of the application, but once created do not get updated if the object definition changes. This article describes the additional capability for a...
