What is routing tracks?

[AaronYang]

Hi,
I was asked a question during an interview for a physical design position: how many tracks do you have in your design in a specific project. (I used Encounter as PNR tool)
Can anyone please give an explanation of what a 'track' is and why it is introduced by the EDA tool?
Thank you all.

A Track is generally used to define the height of a standard cell .So a 9 Track cell will be taller than the a 7 Track Cell. As the routing space horizontally available over the 9 Track is more compared to 7 Track , former will be faster (better driving capacity) and consumes more space than the later.

Hope this answers your query

The Routing Track is a special type of minecart track from the Railcraft mod. This track is used to set the destination of any passing Steam or Electric Locomotive, depending on the Golden Railway Ticket that is placed inside the slot. This can be accessed by using a Crowbar on the track.
