If I know the instant name and its output pin's name. How can I use encounter to get the loading capacitance of that pin? Which command should I use?
Here's an example:
report_property [get_nets [get_property [get_pins DTMF_INST/TDSP_CORE_INST/TDSP_CORE_GLUE_INST/i_962/Y] net_name]]
total_capacitance_max_fall | 0.006total_capacitance_max_rise | 0.006total_capacitance_min_fall | 0.006total_capacitance_min_rise | 0.006wire_capacitance_max | 0.002wire_capacitance_max_fall | 0.002wire_capacitance_max_rise | 0.002wire_capacitance_min | 0.002wire_capacitance_min_fall | 0.002wire_capacitance_min_rise | 0.002
You can query individual values with get_property which should also accept specification of a -view:
get_property -view default_analysis_view_hold [get_nets [get_property [get_pins DTMF_INST/TDSP_CORE_INST/TDSP_CORE_GLUE_INST/i_962/Y] net_name]] wire_capacitance_max
Hope this helps,Bob
In reply to Robert Dwyer:
Does this net capacitance include the input capacitances (gate capacitances) of the input pins connected with this output pin?
Thank you so much Bob.
