RE: Change Pins from VSS to DVDD and vice versa in the Schematic
Well, that code wouldn't work in the layout either. There are several things at issue here: You're searching for the pin name - which almost certainly doesn't matter. You probably want to be changing...

RE: How to find frequency for ring oscillator in Monte-Carlo analysis?
Really? That's a pretty broad question and it's not clear what you don't know. Well, you need to set up your basic simulation - either: Use PSS analysis (in oscillator mode) and then use the Direct...

Hi all, I want to implement a (only 1) bindkey to toggle between leHiMarkNet() and leHiUnmarkNet(). I am not sure how to find out whether or not the current cell view has a net that is being mark by...

RE: bindkey to toggle between leHiMarkNet() and leHiUnmarkNet()
Hi, If the current window does not have a flag set with markNets then you can set it by yourself. if(hiGetCurrentWindow()~>markedNets then hiGetCurrentWindow()~>markedNets = nil leHiMarkNet()...

Ramakrishnan's suggestion of using a flag on the window object to keep track of the toggle state is the best you can do given that there isn't really something to tell you whether anything is marked or...

Alex, Yes, famMap will iterate over families in all the arguments together, so it will work pair-wise as you desire. The second question I can't really answer, as it almost certainly depends on what...
