I am running a full-chip R extraction on a chip,and trying to see the parasitic resistance on some critical nets. When I click on of the net, to see the R of the net. The net is called vdda
It will generate a table like this :
Instance Type Value From To
/rRm 1 R 37.59m /vdda /11:vdda
/rRm 2 R 19.443m /vdda /6:vdda
................
There are about 50 segments here.
If I want to calculate the amount of parasitics resistance in the vdda net, I should add all the value together in series right?
Anyone could comment on this?
I need to know this urgently.
Thanks
Added after 1 hours 45 minutes:
I should just add up the resistance at every segment right? for instance, from the table it should be 37.59mohm + 19.443mohm +......
Any comment on this?
