Optimizing hardware design throughput by latency aware balancing of re-convergent paths
Embodiments herein describe techniques for preventing a stall when transmitting data between a producer and a consumer in the same integrated circuit (IC). A stall can occur when there is a split point and a convergence point between the producer and consumer.

When this condition is met, this means the shortest path has sufficient buffers (e.g., a sufficient number of FIFOs and registers) to queue/store packets along its length so that a packet can travel along the longer path and reach the convergence point before the buffers in the shortest path are completely full (or just become completely full). |
