How to move a Layout Design to Origin (0,0)

manrajgujral
I have made a layout structure consisting of 20 to 30 smaller components plus additional metal paths and pins. This was made as a revision to an older design and after a lot of changes the origin is not at 0,0. Question: How do I move all the components w.r.t each other to the Origin 0,0 ? Meaning I don’t want to skew anything and move the entire layout to 0,0 I had used MAGIC (an educational software for Layout – and not as intimidating as Cadence)during university where we could select the entire layout had a execute a command which then moves everything to the origin. Simple and Sweet. I am having trouble doing the same thing in LayoutL. I am aware of the EDIT-> Advanced->move Origin command, but all it does it provide a x-y cursor which you have to roughly estimate (like taking a shot in a 1st person shoot-out game). It can be made to hit 0,0 with the help of rulers and such, but it isn’t a very elegant way of doing things

  • The origin of a cellview is always 0,0 by definition. I'm assuming you have a point or object in your cellview that you want to be at 0,0. There are two ways to do this.

    1. Select every object in the cellview (be sure all instances, pins and layers are selectable first) and move everything. The Cadence move command prompts for a reference point (if infix is turned off) or uses the point where you initiate the move (if infix is on) as the reference point. Be sure that the point you want to be the origin is used as your reference point and simply move it to 0,0. Be sure that your snap mode is set to anyAngle. If you'd rather not zoom in close enough to find 0,0, after you have started the move, you can type 0:0 in your CIW and press enter and the objects will move to that point.

    2. You can use the Move Origin command as you mentioned. I'm not sure why you think it is a shot in the dark. The coordinates of your cursor shoudl appear in your layout window. If you zoom in close enough, you should be able to put it exactly where you want it. If you are not seeing coordinates in your window, in 6.1, you right mouse click on the banner menu and turn on the Status Toolbar. But your statement about moving the origin to hit 0,0 is not correct. When you are moving the origin, you are moving 0,0 to be somewhere else.

    I hope this helps.
