    摘要： When a first sub-circuit of a programmable integrated circuit (“IC”) is to be deactivated, a global write enable (GWE) signal is deasserted. In response to deassertion of the GWE signal and a first memory cell associated with the first sub-circuit being in a first state, flip-flops in the first sub-circuit are disabled from changing state. In response to memory cells associated with sub-circuits other than the first sub-circuit being in a second state, flip-flops in the other sub-circuits are enabled to change state. When the first sub-circuit is to be activated, the GWE signal is asserted. Logic implemented by the first sub-circuit is preserved between the deasserting and the asserting of the GWE signal. In response to assertion of the GWE signal and the first memory cell associated with the first sub-circuit being in the first state, flip-flops in the first sub-circuit are enabled to change state.

    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： Approaches for mitigating single event upsets (SEUs) in a circuit arrangement. In response to each bit error of a plurality of bit errors, an error address indicative of the bit error in a configuration memory cell in the circuit arrangement is translated into a non-volatile memory address. A partial bitstream at the non-volatile memory address is read from a non-volatile memory. Successive partial bitstreams read in response to successive ones of the bit errors are alternately transmitted to first and second internal configuration ports. A subset of configuration memory cells of the circuit arrangement, including the configuration memory cell referenced by the error address, is reconfigured with the partial bitstream.

    摘要： Method and apparatus for self-checking and self-correcting memory states of a programmable resource is described. Programmable resource of an integrated circuit has a first core and a second core instantiated therein. A first internal configuration port and a second internal configuration port of the integrated circuit are respectively connected to the first core and the second core. The second core is coupled to the first core for monitoring operation of the first core with the second core, and the second core is configured to obtain control responsive to a failure of the first core or the first internal configuration port for a self-correcting mode.

    摘要： A method of securing a design-for-test scan chain within a programmable integrated circuit device (IC) can include placing the programmable IC in an operational mode and responsive to a request to access a scan chain within the programmable IC, selectively enabling a secure mode within the programmable IC according to a configuration state of the programmable IC. Enabling secure mode within the programmable IC can provide access to the scan chain. Responsive to enabling the secure mode, the programmable IC can remain in the secure mode and be prevented from re-entering the operational mode until the programmable IC is power cycled.
