Remember those letters, we'll get back to them in a bit...
First a couple of FAQ's about axes in ViVA.
How can I tell which axis a signal is associated to?
Well, this isn't the easiest thing in the world, but if you look very closely, you'll notice one or more colored bars next to each axis title. They only appear if you actually have more than one axis on your graph, which will happen if you plot quantities of different units (like voltage and current). If you look closely, you'll see that the colored bars on each axis correspond to the colors of the plotted signals associated with that axis.
How can I move a signal from one axis to another (or to a new axis)?
This is easy. Simply select the signal you want to move by clicking on the waveform or it's name in the legend (don't forget you can use the Alt key--one of the sponsors of last week's episode--to quickly see which signal is which). Then, from the menu, select Trace->Assign To Axis and either select the axis you want to move it to or choose New Axis to do just that.
Now a word from our sponsors...
The letters H, V, m & a are the bindkeys you use to create interactive marker measurements in ViVA.
There are several nice things about these markers.
Now you can use the File->Save As Image or File->Print menu to save your beautiful graph to display at your design review.
Is there an equivalent of "aMarker", "bMarker" and "delta Marker" of ViVA in SKILL?
There isn't any way to do this directly, but you can set up the graph with the limits you want, then do File->Save Window to save the graph to a .grf file. Then you can later do File->Load Window and point to that .grf file and use the same or different results database to reuse the setup with a subsequent simulation.
For repeated simulations without changing the graph setup, you can use the "Refresh" plotting mode accessed through the ADE plotting options.
Are there any variable to set range for Y-axes to fixed values e.g. <-200,+200> with using embedded variables? I would like to keep the settings for AC analysis to see magnitude and phase graphs in the same ranges. With this approach the phase margin is easy to read :-)
Thank you for any hints.
