High Fanout Without High Stress: Synthesis and Optimization of High ...

Webusing the FPGA clocking resources. Logic nets with high fanout are the result of a common boolean function driving many other logic blocks. When the number of high fanout nets is large, the high fanout net routing can be sub-optimal and can lead to a high delay penalty when the load or the cells driven by this net are scattered on the die. WebAs best I can tell, no, not quite. fanout_demux_cpu calculates a "hash" using the cpu and the number of sockets in the fanout group, which happens to be smp_processor_id() % num. packet_rcv_fanout then uses this as an index into the array of sockets in the fanout group to determine which socket gets it..
