I'd like to change one net's attribute from signal to clock. One way is using the GUI, attribute editor, which can get the job done. Another way is using the comand, or enven the FE-Database command. so I come the referance, and fine the following, dbIsNetClock, dbSetIsNetClock I found that the dbIsNetClock can not return the proper clock attribute of one net. And, the dbSetIsNetClock can not work either. in the mean time, the related command dbSetIsNetPower and dbSetIsNetAnalog works fine. So I am confused, Is this a tool bug or I miss something and did not use the command properly ?
dbIsNetClock has no direct relationship with the USE CLOCK net attribut.dbIsNetClock is an attribute which is drive by the timer. When the Encounter time your design, it propagate the clock from the clock root definition in your netlist. In the same time it attach this NetClock attribute within the clock network.For CTS, there is another attribute which is call "NetDefInClock". This one is in link with the "USE CLOCK" attribut.Like NetClock attribut, you have access to different command:[i]dbIsNetDefInClock[/i][i]dbSetIsNetDefInClock[/i]Pat.
Thank YOU, That's realy help me a lot.
