    摘要: Approaches for partially reconfiguring a frame are disclosed. In one approach, a circuit arrangement includes programmable resources, frames of configuration memory cells, and partial configuration control memory cells. Each frame includes a plurality of subsets of configuration memory cells, and each subset configures one of the programmable resources. Each partial configuration control memory cell is coupled to a respective one of the subsets. Responsive to a first partial bitstream that includes a quantity of configuration data for all the subsets of configuration cells of a first frame of the plurality of frames, each subset of the configuration memory cells of the first frame is configurable or not configurable responsive to the state of the associated partial configuration control memory cell.

    摘要: In a programmable device employing antifuses, first digital logic transistors the gates of which will experience a programming voltage Vpp have a greater gate insulator thickness than do second digital logic transistors the gates of which will not experience the programming voltage. The first digital logic transistors may be logic module input device transistors. The first digital logic transistors may be transistors coupled to an enable input lead where the enable input lead is couplable to a tie-high conductor or to a tie-low conductor depending on which of two antifuses is programmed.

    摘要: A programmable integrated circuit (see FIG. 18) includes a plurality of interface cells with programmable antifuses disposed on a branch of a routing conductor. The routing conductor extends in a first direction and is coupled to one terminal of a programming transistor. The other terminal of the programming transistor is coupled to a programming driver via a programming conductor that extends in the first direction. The branch of the routing conductor crosses a plurality of routing wire segments of one of the interface cells, where programmable antifuses are disposed to couple the branch of the routing conductor to one or more of the routing wire segments. The routing wire segments extend parallel to one another in the first direction and are each coupled to a first terminal of separate programming transistors. The second terminals of the programming transistors are coupled to programming drivers via programming conductors that extend in a second direction, which is perpendicular to the first direction. Thus, the programming drivers for the routing wire segments and the routing conductor are positioned in different locations. Accordingly, when an antifuse is programming to couple the branch of the routing conductor with one of the routing wire segments, the two programming drivers are controlled by two different programming control shift registers.

    摘要: Internal net drivers of a field programmable gate array are laid out with additional transistors to increase current drive capability at low supply voltages when a low supply voltage mask option is used. When a high supply voltage mask option is used, the additional transistors are not used in this way and the net drivers do not provide additional switching current drive capability. In some embodiments, were a low supply voltage mask option net driver operated at the high supply voltage, an impermissibly large switching current would flow through a programmed antifuse in a net coupled to the output of the net driver.

    摘要: A programmable integrated circuit (see FIG. 9) has a plurality of L-shaped programming power buses (for example, 126, 130, 129 and 127) that extend along sides of the integrated circuit. Each L-shaped programming power bus extends along two adjacent sides of the integrated circuit such that legs of two L-shaped programming power buses extend along each of the sides. There are four pluralities of programming drivers (for example, 110, 117, 115 and 112), one plurality being associated with each of the four sides. There are also four programming current multiplexers (for example, 118, 125, 123 and 120), one associated with each of the sides. A programming driver of one of the plurality of programming drivers is selectively couplable to one of the two L-shaped programming power bus legs that extends along the associated side of the integrated circuit via the programming current multiplexer associated with that side. Additional pluralities of programming drivers and additional programming current multiplexers can be provided.

    摘要: A programmable integrated circuit such as a field programmable gate array (see FIG. 3) has a few long routing wire segments for transmitting signals long distances across the integrated circuit. These long routing wire segments can be coupled together with programmed antifuses. A high-drive output driver may be used to drive signals a long distance through such coupled together long routing wire segments giving rise to large switching currents across the programmed antifuses that couple the long wire segments together. In some types of antifuses, programmed antifuse reliability is dependent upon maintaining the programming current used to program the antifuse a certain factor greater than the peak switching current flowing through the antifuse during normal operation. The antifuses in these long wire segments therefore should be programmed with proportionately larger programming currents. To increase the programming currents with which these antifuses are programmed, programming current is supplied onto each of the long routing segments from two different programming conductors via two different programming transistors.

    摘要: A field programmable gate array has columns of logic modules. A programming conductor used to conduct programming current to program antifuses of the field programmable gate array extends between two adjacent columns of logic modules. First wire segments extend from the programming conductor and toward the logic modules of a first of the two adjacent columns. Second wire segments extend the opposite direction from the programming conductor and toward logic modules of the second of the two adjacent columns. Programming current used to program antifuses disposed along the first wire segments as well as antifuses disposed along the second wire segments can be supplied from the same programming conductor that extends between the two columns of logic modules. The logic modules of the first column are mirrored versions of the logic modules of the second column.

    摘要: An interface cell for a programmable integrated circuit includes a pad, an input buffer, a first routing conductor, a plurality of second routing conductors, and a plurality of antifuses. The input of the input buffer is coupled to the pad and the output of the input buffer is coupled to the first routing conductor so that an input signal from the pad can be supplied onto the first routing conductor without passing through any programmed antifuses. The second routing conductors extend parallel to one another in a direction perpendicular to the direction in which the first routing conductor extends. The second routing conductors cross the first routing conductor and then pass out of the interface cell and into a routing channel of the programmable integrated circuit. One of the antifuses is disposed at each location where one of the second routing conductors crosses the first routing conductor. Accordingly, an input signal from the pad can be supplied onto any desired one of the second routing conductors of the routing channel by programming only one antifuse. The interface cell contains an enablable register, the control inputs of which can be independently driven from any conductor in the adjacent routing channel. Combinatorial and registered outputs of the interface cell can be simultaneously routed to the routing channel and some interface cell outputs have 2.times. drive strength.

    摘要: To facilitate the simultaneous programming of multiple antifuses on an integrated circuit, a first current path is established from a first programming terminal (VPP1) of a programmable logic device through a first antifuse to be programmed and a second current path is established from a second programming terminal (VPP2) of the programmable logic device through a second antifuse to be programmed. By supplying the programming current for programming the first antifuse from a different terminal than the programming current for programming the second antifuse, the two antifuses can be programmed simultaneously with an adequate amount of programming current being supplied to each antifuse. A programming current multiplexer circuit is disclosed for selectively coupling either a first programming voltage (VPP1) terminal, a second programming voltage (VPP2), or a ground terminal (GND) to a programming bus and/or to an antifuse to be programmed. The first and second current paths can be established using multiple such programming current multiplexer circuits.
