WebIt sounds like you may be trying to implement something like the report_high_fanout_nets command. You could also try using all_fanin and all_fanout commands to get the actual fanin/fanout for each net, then just take the length of the array or something. Depending on the size of your design this could potentially be a pretty slow process. 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.. Once you see that the whole design of the …
