    ruler in virtuoso Layout L - problem solved Reply

     Hi all,

     Thanks for the wonderful community!

     I am a student at University of Texas Dallas and am a regular user of cadence for layouts.

    the new version of cadence - ie 6.1 was recently installed in our system. The interface is fine, but I am facing problem during drawing layouts. The ruler seems to work fine when nothing is drawn (layout is empty). As soon as even a small of rectangle (of poly of length =0.1u and height = 0.3u, say) is drawn, it will become impossible to draw a ruler at any place other than that poly. And the ruler fixes itself to the dimensions of poly i.e we can only draw rulers of 0.1u distance or higher. Basically, the pointer moves only around that rectangle and cannot be found anywhere else.

    If I delete that poly, then everything functions normally - we can draw rulers of any resolution. This problem is not only with rulers but with anything that one tries to do after drawing poly(or any rectangle).

     Hope I have explained the problem right. I was wondering if anyone had the same problem before. Please suggest a possible solution. 

    Thanks in advance

     sounds like you need to play around with the snap size and gravity. snap spacing can be set in the Display Options and gravity can be set in the Layout Editor Options (in IC5141, I'm not sure if the menus are the same in IC6x).

     Hi,

    thanks khan, thank you all. The problem was with the .cdsenv file in the home directory. I deleted the file and it seems to work now.

    regards, Vikas
