Report Generation
Fanin and Fanout Reports
The fanin and fanout reports are generated using the following commands:
report_fanin [-level integer] [-tristate] [-sequential] [-hierarchical] [{> | >>} filename] [-maxline integer] list_of_pin_path_or_id
report_fanout [-level integer] [-tristate] [-sequential] [-hierarchical] [{> | >>} filename] [-maxline integer] list_of_pin_path_or_id
where:
■filename is the name of the generated report file. If filename is given, the report is written to the file. If the filename is omitted, the report is displayed on the standard output.
■list_of_pin_path_or_id is the Tcl list of pin or port path names or object identifiers for which to start the fanin or fanout cone search.
The -hierarchical option allows the command to traverse backwards across hierarchy boundaries to generate a report. By default for fanin, it will stop at the input port and it will report on the fanin path starting from that port (treated as the start point). By default for fanout, it will stop at output ports and report the fanout path ending to that port (treated as the end point).
The -level option specifies the number of levels which need to be traversed for generating the report.
The -maxline option TBD.
The -tristate option includes the tristates in the path.
The -sequential option includes the sequential cells in the path. By default the reporting stops at the encounter of the first sequential cell in the path.
