Skill code for finding coordinates of selected instances in the layout

can u please guide me in the regards,

 Rather than bury this as a sub topic, why don't you ask it as a new topic.

 You will have to open the file and parse its format. fscanf can do that depending on the format. See the command in help documentation.

The command to place instances is dbCreateInst.

 Depending on what you mean by checking if the layout is on grid, you may be better off using a DRC checker as there may be a lot of data to process. If it the concern is only the instance placement, snap it to grid before placing the instance.

Arjun,

You asked the same question 4 times (two new posts in two forums, and adding to two existing threads). That will simply annoy people and not get you an answer any quicker. Please do not do that.

I'll merge your posts together to avoid confusion.

Hi Andrew,  

Can u please tell me how to change the coordinates or bBox of the device using skill

I'm not sure why you are asking me (since I had nothing to do with the original thread other than making a moderator comment), who "u" is (it's not a word in the English language), or why you're posting on a thread that is over 7 years old. Please read the forum guidelines.

I assume you just want to know how to do:

instId~>xy=newCoord

Kindest Regards,

Andrew

Rather suspiciously I had a rather similar question in a friendship request (I don't normally accept friendship requests from people I don't know or people I haven't asked to do this when they can ask the same question in the open forums):

Friendship request: munna sk

Hi Sorry for this personal message. I don't know how to put a question so that's why I put here I want to know how to change the bbox of the instance.  I tried Instance~>bbox=new bbox values But it gives result as nil Can u please tell me how to change the bbox of the instance

Learn more about munna sk.

The simple answer is, you can't. The bBox is defined by the bounding box of the shapes/instances etc within the cellView that has been instantiated, offset by whatever the origin of the placed instance is. You can set Instance~>xy and then the bBox will shift to around the new origin.

It would make no sense to be able to set the bBox.

Andrew.

Why I am asking is I need to flip all the devices which are selected. But at the time I am able to flip the devices but the coordinates are changed but I am unable to change the device placement to the previous coordinates. I am unable to do this with instance~>xy command because I observe that two different positions has same xy coordinates. How can I move the device to previous place.. Can u help me..?

In that case you need to set the ~>orient (or maybe ~>transform) attribute of the instance, or use dbMoveFig() to move with a transformation. Take a look at this post: for some code that shows how to do flipping easily.

I don't know what "u" is unless you were murdering the English language and meant "you". There's no tax on characters in this forum so please write properly rather than using instant messaging shorthand. For an Englishman this is rather jarring...

Regards,

Andrew.
