a question about ansys totem ir drop analysis.

joyeongjun

1. To see the IR drop, which analysis should be performed?

2. Can I see ir drop in static analysis?

3. Please tell me the reason why def and lef are duplicated in the gsr file in the dynamic analysis.

4. Is a library file (.lib) required to characterize blocks in dynamic analysis?

5. Should I extract the STA timing by verilog modeling the Analog Block in the dynamic analysis? So, can I see the full IR drop in the dynamic analysis?

6. Do I really need to put the lumped model of the pad in dynamic.tcl?
setup package -power -r 0.005 -l 1 -c 5
setup package -ground -r 0.005 -l 1 -c 5
setup wirebond -power -r 0.01 -l 2.2 -c 1.42 -ground -r 0.05 -l 1.7 -c 0.2
setup pad -power -r 0.001
setup pad -ground -r 0.001

7. Please tell me the options that must be included in Ansys Totem dynamic analysis.

static and dynamic analysis all can check IR Drop

-->they are two different circuit description format, totem can parse circuit base on them

4. Is a library file (.lib) required to characterize blocks in dynamic analysis?
-->what's format about library file?you'd better show am example to us

5. Should I extract the STA timing by verilog modeling the Analog Block in the dynamic analysis? So, can I see the full IR drop in the dynamic analysis?
--> STA file is an optional, yes, we can see power and signal EMIR drop in dynamic analysis
