Title: Re: EE Times commentary: analog layout automation Post by didac on May 20th, 2007, 11:54pm Good article, it explains very clear which are the main problems of analog layout and how must be the solution. The only sad thing for me is that I must hurry to get the Phd or at the lab I will be obsolete as "layout man"... |
Title: Re: EE Times commentary: analog layout automation Post by krishnap on May 23rd, 2007, 7:25am Articel gives good insight on the needs for analog layout automation. Currently few options like autorouter , where precesion is not important and pcells for bigger modules etc are giving some speed. |
Title: Re: EE Times commentary: analog layout automation Post by weber8722 on Oct 29th, 2012, 7:16am Hi, reading this article from 5/17/2007 now - 2012 - I think not much has changed at all!!! :( For most non-trivial circuits, like having 40 transistors most autoplacer fail, although a good designer can find a solution quickly. The constraint concept ends up with adding more and more constraints, till you have no overview anymore or run into over-constraintment or tool problems! Take a look at "Deterministic Analog Circuit Placement using Hierarchically Bounded Enumeration and Enhanced Shape Functions", 2010. This paper describes an advanced placer, but the created layout would NEVER survice a real-world design review :'(. It seems that our PhD workers like to create new and more algorithms, but not even have criteria or benchmark to decide what a good layout is! Bye Stephan |
