Abstract: 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.

Abstract: Various approaches for generating an implementation of an electronic circuit design are disclosed. In one approach, a software portion of the design is compiled into software that is executable by a hard processor disposed on a single semiconductor chip with resources of an programmable logic device (PLD). A first synthesized version of a hardware portion of the design is generated for the PLD. A synthesized memory scrubber having an empty block for an address counter is generated, as well as a triple modular redundant (TMR) address counter. The memory in the first synthesized version of the hardware portion of the design is replaced with the memory scrubber, and a complete set of netlists is generated, including a TMR hardware portion of the design and a single instance of the synthesized memory scrubber. A configuration bitstream is generated from the complete set of netlists and stored for later use.
