Reports the results of clock tree synthesis. By default, the report includes the following information about the clock tree:
Library information, such as the clock name, mode, library name, operating condition and PVT values.
Clock tree structure information, such as the number of subtrees, sinks, and buffers, and the maximum and minimum trigger edge delay at sinks.
Delay, skew, and transition values, such as the rise and fall phase delay, skew, buffer transition, and sink transition values.
Maximum transition time violations
Skew distribution information, such as the input and output delay ranges.
Macro model information, such as the maximum and minimum trigger edge delay at sink values.
AC current density violations
The reportClockTree command also reports power information if you specify setCTSMode - powerAware true and include the Period statement in the clock tree specification file. The report includes information on the total net switching power, internal clock instances power, internal leaf pin power, and leakage power. For more information, see Power Information in the "CTS Report Descriptions" section of the "Synthesizing Clock Trees" Chapter of the EDI System User Guide .
In multi-corner mode (setCTSMode -multiCorner true), the reportClockTree command reports the trigger skew value for all active analysis views in the design, and reports other analysis information, such as the phase delay and transition values, only for the default analysis view.
Note: Multi-corner CTS does not support reportClockTree -localSkew. |
