Forum Post: RE: What's the difference between 'all' and 'allpub' in the save options form of ADE L?

This is a spectre choice. The "allpub" choice means all signals that are "normally useful" - so this means all voltages at all external pins of devices. When you pick "all" it adds saving of some internal nodes - so transistors may have internal nodes the other side of the drain, source, gate resistances which aren't usually that helpful. It also saves internal nodes within VerilogA modules. Usually "allpub" is sufficient. It does not affect what is simulated, just what signals are saved. Andrew.
