Net Highlighting without appearing staggered lines

Not sure what you mean by "staggered lines". Do you mean the arcs shown above (the picture is quite small)? If so, they are shown when you have the same net in multiple parts of the schematic which are connected by name rather than physically, If all nets are wired physically together, you don't get the arcs...

I mean the nets are wired physically together, but they don't show the arcs.
I need the arcs, because they can let me trace signal quickly.

I struggle to see how the arcs add value in that case (or even where they would be drawn). The physically connected nets are already highlighted entirely in purple; the arcs are added to show connections between separate physically connected islands - and there are no islands in this place (so where would it draw the arcs between?)

as bellow pic, the nets (power pins) are Highlight without arcs.
when circuit is huge (in single schematic), the arcs are helpful for me.

In that picture (not sure why you uploaded it somewhere else - it's also rather hard to see), it appears that you have multiple islands which are not physically connected to each other (you said they were earlier).

It's probably this: VSE: How to disable the arcs in dynamic net highlighting for labeled nets?

Take a look at Options->Display, and if you have "Connect by Name Highlighting" turned off, turn it on (the default is normally on, but maybe the cdsenv var mentioned in the article above has been changed in your environment).

Virtuoso@6.1.7  Options->Display has Connect by Name Highlighting option.
I can change Virtuoso version to solve this problem now, thanks a lot.
