net input transition calcuation

[devop]

hi all:
when we use

report_delay_calcuation -from -to


If the two pins are the source and sink of an interconnect, it reports the wire delay and degraded slew across the wire.

Can anyone give me the formula of how to get the delay and slew???Thanks a lot

hi,

my 2 cents,

i dont know whether i understood the question correctly,

just do report_timing -from -to -trans -cap,

this will help to know the delay and transition values

myprayers,
