The .lib has power consumption numbers, yes - but it does not have a physical representation of the power grid inside the cell with current tap locations, etc.
Why do we need power grid view for rail analysis as we will be having .lib with power numbers for all std cells? Please clarify
Hi kkishore, Please post your question to the Digital Implementation Forum. Thanks!
i was doing eps for block level and i was a fresher for digital implementation, i was supposed to give pad locations for static rail analysis but as i said for block level i couldn't it was asking to give atleast def pins/voltage boundary file, i have no idea to get them, can u help me plz
Hi Dlleep, Please post your question to the Digital Implementation Forum. Thanks!
Can you please help with the set up for rush current analysis.
Actually I am getting error as " ERROR (VST-1190): The always-on rail for the switched rail "VDDAONINT_DH" in not found inthe design. The always-on rail name must be in the netlist of the power-domain specification, if doing power-domain based power-up analysis, or must be the name of the rail to be analyzed, if doing net based power-up analysis" while running rush current analysis.
Howard, you're in the right place for displaying the results of IR drop, but it sounds like you didn't actually run the IR-drop yet. Check the User Guide, then if you still have questions, I think starting a thread in the Digital Implementation forum would be better than us trying to solve it here. You'll get more eyes on your questions, and it's easier to post pictures and things that may help in debugging any issues. Thanks for participating in cadence.com! Look forward to seeing you on the forum...
Hi Kari: After I ran through your script (modified to my design), I tried to analyze IR-drop. I tried to start from "Power->Report->Power & Rail Results". But for the "Plot" section -> Rail Analysis Plot Type", I can't choose IR-drop. Did I lose anything? Thank you!
Howard: Yes, you can. Pretty much everything you can do in EPS, you can do through the EDI cockpit as well.
Hi Kari: Another question. After generating power library, can I proceed to run IR-drop analysis?
Hi Howard, If you have your design loaded in EDI, just leave out the read_lib part and try it. (You may also want to remove the "exit" at the end of the script.)
Hi: I am wondering if I just have EDI and psviewer, where I can use these script? I tried "read_lib" in encounter, but it's an invalib command name.
Nice Article on Power Model Creation.
