Abstract: Methods and apparatus for extracting a setting of configuration bits to create an exclusion configuration for providing protection against peek and poke attacks in a multi-tenant usage model of a configurable device is provided. The device may host multiple parties that do not trust each other. Peek and poke attacks are orchestrated by tapping (peeking) and driving (poking) wires associated with other parties. Such attacks may be disabled by excluding the settings of configuration bits that would allow these attacks by other parties. This set of configuration bits that should be excluded for preventing all peek and poke attacks creates the exclusion configuration. Methods are described that disable a particular class of peek and/or poke attacks through the use of partial reconfiguration. Methods and apparatus are described to dynamically detect peek and/or poke attacks.

Abstract: An apparatus to facilitate enabling secure state-clean during configuration of partial reconfiguration bitstreams on accelerator devices is disclosed. The apparatus includes a security engine to receive an incoming partial reconfiguration (PR) bitstream corresponding to a new PR persona to configure a region of the apparatus; perform, as part of a PR configuration sequence for the new PR persona, a first clear operation to clear previously-set persona configuration bits in the region; perform, as part of the PR configuration sequence subsequent to the first clear operation, a set operation to set new persona configuration bits in the region; and perform, as part of the PR configuration sequence, a second clear operation to clear memory blocks of the region that became unfrozen subsequent to the set operation, the second clear operation performed using a persona-dependent mask corresponding to the new PR persona.

Abstract: An apparatus to facilitate scalable runtime validation for on-device design rule checks is disclosed. The apparatus includes a memory to store a contention set, multiplexers, and a validator. In one implementation, the validator is to: receive design rule information for the multiplexers, the design rule information referencing the contention set, wherein the contention set identifies a determined harmful bitstream configuration for each multiplexer instance of the multiplexers, and wherein the contention set comprises a mapping of contents of a user bitstream to configuration bits of the multiplexers; receive, at the validator of the apparatus, the user bitstream for programming the multiplexers of the apparatus; analyze, at the validator using the design rule information, the user bitstream against the contention set at a programming time of the apparatus; and provide an error indication responsive to identifying a match between the user bitstream and the contention set.

Each of the regions in the second IC die is vertically aligned with at least one of the sectors in the first IC die. Each of the second router circuits is coupled to one of the first router circuits through a vertical die-to-die connection. The first and second programmable interconnection circuits are programmable to route signals between the programmable logic circuits and the non-programmable circuits through the first and second router circuits.
