Run a scripts including a set of commands: "source fanin.tcl"
Command for obtaining fanin: "all_fanin -to icpu_adr_o[31]"
PS:
1. Often the initial libraries are set as
set search_path "/auto/edatools/synopsys/syn/v2006.06-SP4/libraries/syn"
##set TECH_DIR $synopsys_root/libraries/syn
set target_library class.db
set symbol_library class.sdb
set link_library class.db
2. If some of the results are not printed out. Add -verbose option, so "source -verbose fanin.tcl". And add a command line in fanin.tcl
"set collection_result_display_limit 220000" a large number.
