set_global report_timing_format {hpin cell delay arrival incr_delay slew load fanout} Use this command before reporting timing. You will able to load capacitance value on the output of the cell in the timing report. Encounter call TQRC extraction engine to extract RC value after postroute. TQRC is a part of encounter. Stand alone IQRC engine licence is also available from cadence. It extract RC value and save them in current working directory with rcdb extension. If you want to see full details dump out a spef by using rcOut command. Encounter uses CTE (common timing engine) for timing. A stand alone ETS (Encounter Timing System) is available as a separate license. ETS is timing sign-off tool from cadence.
I used rcOut to get spf and spef file. But I prefer to get the interconnect delay information.
I saved the timing report, but I only see the gate delays (shown as following).
How does CTE calculate the intrconnect delay?
I don't know the variable set in Encounter, but if you don't report the nets, the report will not show you the RC values. From your report, only i/p and o/p pins of the cells are shown, no net info between 2 cells. Please report the nets, you will see the RC values
