Abstract: Embodiments herein describe reconfigurable integrated circuits (ICs) which include programmable logic that can be configured to perform a user task. In one embodiment, the programmable logic is configured as an accelerator. The user may want to gather debug data or profiling data when executing the accelerator. Rather than using debug/profile circuitry disposed in a static region of the IC, the user can provide preferences to a linker which then dynamically configures debug/profile circuitry in a dynamic region of the IC. That is, based on user preferences, the linker can generate customized debug/profile circuitry for monitoring the performance of the accelerator. In one embodiment, the debug/profile circuitry is implemented in the dynamic region of the IC and is tailored to user preferences rather than relying on static, or fixed, debug/profile circuitry. Moreover, the user can retrieve the debug/profiling data on demand using a call back and a device driver.

Abstract: Disclosed approaches monitor states of a plurality of sets of a plurality of handshake signals. Each set of handshake signals is associated with a respective one sub-circuit of a plurality of sub-circuits. For each sub-circuit, a beginning of an iteration by the sub-circuit is detected based on states of the plurality of handshake signals of the set associated with the sub-circuit. A graphics object is generated in response to detecting the beginning of the iteration. The graphics object is displayed on a display device and overlaid on a timeline associated with the sub-circuit. The graphics object has a bound that corresponds to the beginning of the iteration. The end of the iteration is detected based on the states of the associated set of handshake signals, and the graphics object is bounded on the timeline to indicate the end of the iteration.
