It looks the specctra doesn't run, but the edit--> zoom in can works. Why?
Have any guy encounterred this problem?
If you question is about middle mouse zooming, middle-click and release, center at picked point, middle-click and drag, left and up, zoom in, right and down, zoom out. In more recent times, Specctra is more aimed at automatic routing, rather than route editing.
Hello on a 2 button mouse with a scroll wheel that can be pushed to act as a third button, in specctra you push the scroll wheel down and then drag to zoom in and out or move around the board.
Specctra is a old router product that has been around for ever and the way it works is by design. The zoom in out etc is very fast using a a 3 button mouse or 2 button mouse with a wheel that doubles as a third button.
In Allegro the zoom in and out is more Obvious :)
No Specctra is not dead, Cadence still support it as far as I am aware.
It is a very good tool and for interactive routing it is excellent. For full autorouting though better routers do exist, but they are not
modern as in supported anymore.
Specctra is kind of like a swiss army knife.. It can do many things.
