dbcommands

ArvindBezawada

Hi how to give adress of timing library and other valuies using this command

 dbNetEvalDelayAndTran netPtr timeArcPtr rise_delay(ns) rise_trans(ns) fall_delay(ns) fall_trans(ns)

 RightNow for reporting slew value of a net using "reportNet -net net_name"..This is taking longer time ..if it is a post route database it is

going for full chip extraction and then it is reporting so can we use any dbget command as alternative.......

  • I think the best way to query values like these are with the Advanced Timing TCL commands like these for example:

    encounter 1> get_pins DTMF_INST/TDSP_CORE_INST/i_10084/Y
    encounter 2> report_property [get_pins DTMF_INST/TDSP_CORE_INST/i_10084/Y]
    max_transition                      | 4.500
    slew_max_fall                       | 0.398
    slew_max_rise                       | 0.739
    slew_min_fall                       | 0.398
    slew_min_rise                       | 0.739
    encounter 10> get_property [get_pins DTMF_INST/TDSP_CORE_INST/i_10084/Y] slew_max_rise
    0.739
    A nice thing about get_property is that you can specify which MMMC view you want query:
    encounter 11> get_property [get_pins DTMF_INST/TDSP_CORE_INST/i_10084/Y] slew_max_rise -view setup_func
    0.739

    Think these will help meet your needs?
