    摘要: A multiplexer that can be used, for example, in a programmable logic device (PLD). The multiplexer includes a plurality of pass transistors passing a selected one of several input values to an internal node, which drives a buffer that provides the multiplexer output signal. The pass transistors can be controlled, for example, by values stored in memory cells of a PLD. The pass transistors have a first oxide thickness and are controlled by a value having a first operating voltage. The buffer includes transistors having a second and thinner oxide thickness, and is operated at a second and lower operating voltage. Where memory cells are used to control the pass transistors, the memory cells include transistors having the first oxide thickness and operate at the first operating voltage. Some embodiments also include transistors of varying gate length for each of the pass transistors, buffer transistors, and memory cell transistors.

    摘要: A structure that can be used, for example, to implement a lookup table for a programmable logic device (PLD). The structure includes configuration memory cells, pass transistors, and a buffer. The pass transistors pass the output of a selected configuration memory cell to the buffer, and are controlled by data input signals of the structure. The pass transistors have a first oxide thickness and are controlled by a value having a first operating voltage. The memory cells and buffer include transistors having a second oxide thickness thinner than the first oxide thickness, and operate at a second operating voltage lower than the first operating voltage. The data input signals are provided at the first operating voltage. Some embodiments include data generating circuits that include transistors having the first oxide thickness. Gate lengths can also vary between the memory cell transistors, pass transistors, buffer transistors, and data generating circuits.

    摘要: Method and apparatus for regulating voltage within an integrated circuit is described. For example, a voltage regulator receives a first reference voltage and produces a regulated voltage. A comparator includes a first input for receiving a second reference voltage and a second input for receiving the regulated voltage. The comparator includes an offset voltage. The comparator produces a control signal indicative of whether the difference between the second reference voltage and the regulated voltage is greater than a predetermined offset voltage. A clamp circuit clamps the regulated voltage to the second reference voltage in response to the control signal. In another example, the clamp circuit is removed and a multiplexer selects either a first reference voltage or a second reference voltage to be coupled to a voltage regulator. The multiplexer is controlled via output of a comparator that compares the first reference voltage and the second reference voltage.

    摘要: Method and apparatus for data monitoring for error detection is described. A programmable logic device includes a configurable logic block having function generators, each of which is configurable for at least two programmable mode functions. The function generators are coupled to an array of memory cells for storing configuration bits for configuring the function generators. A primary address line is coupled to each memory cell spanning two or more of the function generators. A secondary address line is coupled to groups of memory cells associated with the function generators. A mask circuit is configured to selectively communicate a signal of the primary address line to a segment of the secondary address line or to a ground responsive in part to the program mode function.

    摘要: A test circuit to test rise delay/fall delay performance on a semiconductor device may comprise a latch to latch data at its input responsive to a clock signal. The latch may source an output signal related to the data latched. A buffer chain may be configured to serially propagate the signal sourced by the latch from the latch output back to the clock input, as the clock signal. A reset/set input of the latch may be configured to receive a reset/set signal from an intermediate node of the buffer chain.
