RC response[TUI-39]after "report clock_gating"

cwwang over 10 years ago

Hi All,

After "synthesis -to_mapped",when issuing "report clock_gating" command. The following error message appears:

======

Error : Invalid or missing object for the attribute. [TUI-39] [get_attribute]

: An object was not specified or the specified object was an invalid object type. There are 4 valid object types that can be specified as the final (third) argument when getting the 'lp_computed_toggle_rate' attribute. Valid objects are: pin, subport, port, and net.

======

Although I can still write out the mapped netlist and sdc. But failed at the following command "write_et_atpg".In other words, no atpg database and I could not ignore this error. Someone tell me that RC may encounter some problem while trying to insert gated cell. But the log file did not show such a problem after "synthesis -to_mapped" command. I had checked the netlist and found that cells with RC_CGXX exists. I think that clock gated may works. Would you help me to solve this issue?Or tell me what else could I check.Thanks!

Problem solved by Cadence AE. The root cause is that RC10 had a bug while calculating toggle rate of a design with clock gating turned on. This issue had gone while using RC13.
