I thought in the past that it would be easy for modified nodal circuit analysis programs to print and plot the node conductance for dc and transient refered to the global gnd-node. I requested this feature about 15 years ago while using SMASH. It is very useful also for general analog circuits which have different switchable operating modes or at least a power down mode. Often the circuit leakage is defined by a floating node and an active gate. The potential on this node is in practice defined by leakage current corners. All designkits which I work with in the past have wrong distributions and could not detect the floating node issues.
About 10 years after the feature request SMASH implement this. But now on the kits does not have the corners and I am not using SMASH anymore.
