WAVE VIEWING
Spice simulation data can be viewed directly in Xschem.
  
   -  Overlayed and stacked analog / digital waveforms, cross-probing of nodes into graph
-  Simple RPN notation for entering waveform expressions (average, power, derivative,...)
-  Cursors for time / delay / amplitude measurements
-  Graph configuration (zoom, waveforms, colors) is saved with the schematic
