The method of declaring an edge rate or Frequency is using IBIS models assigned in CES.
There are a few options within HLDRC besides using the IBIS model.
1. You could create your own model and assign to the pins/nets
2. There is a Global setting for Edge Rate Setup-Options –Default Values (This must be set before the HLDProj file is created).
3. Select the Net and in the properties dialog change the value for Rise and Fall Times
I hope that this is helpful information for you.
Thank you Ed, this is really helpful!
I've realized that in my case, I don't have Rise and Fall Time (also other parameters as Voltage Swing) in the Net Properties Dialog...so I can't change their value as you said in option 3:
Do you have any idea to solve it?
About option 2 I can't use it because I need to change these type of parameters depending on nets, so each net should have its own edge rate, frequency...Finally, option 1 would be helpful but I suppose that it's more complex than option 3 so if I can fix the explained problem it wouldn't be necessary.
