Command for getting only the si delay

ssuhas

Hi,

I wanted to know the si delay added after performing SI analysis.

Can anyone let me know the command to get only the SI delay of the nets

 

Thanks

    You can also use the  timing Tcl API to query the net arcs directly for the delta delay values:

     

        set delta_delay_max_rise  [get_property [get_arcs -from U1/Y -to U2/A] delta_delay_max_rise]

     

    There are similar properties for min delays and for falling delays.  Refer to the get_property command
    which is documented under the "Advanced Timing Tcl Scripting Commands" in the EDI or ETS
    Command Reference document.

    Note: Queries on arc delays are not yet MMMC aware - you cannot use the get_property -view qualifier
             yet to query on a view-specific basis.
