Abstract:
Methods and circuits are disclosed for backing up the value of a bi-stable circuit included in a set of programmable logic circuits of a programmable IC. The programmable logic circuits are configured to implement logic circuits having functions based on data values stored in a used portion of a plurality of configuration memory cells. The programmable IC includes a backup control circuit configured to back up and restore the value of the bi-stable circuit. In response to a first signal, a first data value stored by the bi-stable circuit is retrieved and stored in a first one of the plurality of configuration memory cells that is unused in implementing the logic circuits. In response to a second signal, the first data value is retrieved from the first one of the plurality of configuration memory cells and stored in the bi-stable circuit.
Abstract:
An apparatus relating generally to an error detection system is disclosed. The apparatus includes a first data bus and a second data bus. A first circuit is coupled for communication via the first data bus. A plurality of storage elements are coupled to the first data bus and the second data bus. A second circuit is coupled for communication via the second data bus. The error detection system is coupled to the first data bus and the second data bus. The error detection system is coupled to compare first data on the first data bus with corresponding second data on the second data bus. The error detection system is configured to generate an error signal responsive to mismatch between the first data and the second data.
Abstract:
A method, non-transitory computer readable medium, and apparatus for performing fault injection and verification on an integrated circuit are disclosed. For example, the method generates a mask file for one or more modules of a hierarchical design, wherein the mask file identifies one or more essential bits, receives a selection of one of the one or more modules as a selected module for the fault injection and the verification to be applied, performs the fault injection on at least one essential bit of the selected module based upon the mask file for the selected module, and performs the verification on the selected module.
Abstract:
A method, non-transitory computer readable medium, and apparatus for performing single event upset detection and correction are disclosed. For example, the method comprises: setting, by a processor, at least one starting address for each of a plurality of rows of a design for an integrated circuit, setting, by the processor, at least one ending address for each of the plurality of rows of the design, and performing, by the processor, the single event upset detection and correction scan in parallel, from the at least one starting address for each of the plurality of rows to the at least one ending address for each of the plurality of rows.
