Abstract
Inter-kernel dataflow analysis and deadlock detection includes, for each kernel of a plurality of kernels of a design, including, using computer hardware, a signal for the kernel that is asserted in response to all processes inside the kernel stalling, wherein the plurality of kernels form a strongly connected component. For each kernel of the plurality of kernels, the signal is asserted during operation of the design in response to each process in the kernel stalling. A notification is generated indicating that the strongly connected component is deadlocked in response to each kernel of the strongly connected component asserting the signal.
