layout instances name connected in a selected net.

Hi Marbs

If you are using IC614, you can find the instances on the net as follows:
a. In navigator, right mouse click on the net
b. Go to "Select->Instances on net"

The instances will be highlighted in both navigator and layout. When posting questions, it would be good to state the version of Virtuoso which you are using:

linux>icfb -W
linux>virtuoso -W

Hi Quek,

I am using Icfb version 5.10.41.500.5.109.  I am sorry for not specifying

my icfb version. How to make a SKILL file to display all the instances name

that is connected to a particular net in the layout ? for my version.

Thanks in advance,

Marbs 

Hi Andrew,

Thank you for the code, but what I want to display are only the layout instances name

that are presently connected in the selected wires(M, SM, TM ), not all its complete

connection as it is stated in schematic.

For example:

net 94 schematic connection is |Q23.B , |Q23.C , |Q24.B and |Q25.C

 but in my layout :

net 94 is only connected to |Q23.B and |Q24.B  

If I select the wire in layout  presently connected to  |Q23.B and |Q24.B

The output in CIW must be : The selected net net 94 is presently connected to |Q23.B and |Q24.B . Wire in layout

                                          not yet complete .

I am sorry for  not clearing my first message.

Please help.   

Regards,

Marbs 

 I'm afraid I don't know of a way of accessing this kind of information from Virtuoso Layout XL - it's known internally. In IC613/IC614 you could probably inspect the markers used by the annotation browser for showing incomplete nets, maybe.

Otherwise you'd probably have to use some dbGetOverlaps() type function to see if the pin figures associated with the terminal associated with each instTerm on the net are covered by a shape which is on the same net. Even then, it wouldn't tell you whether there are gaps in the routing - in that case, how would you decide which are connected and which aren't?

Regards,

Andrew.

Hi Andrew!

Is there any way to obtain the devices connected on a net from the schematic view?

Please read the Forum Guidelines. You've asked a question in a 9 year old thread which is about layout instances, and you're asking about instances on a schematic. So that's at least two of the forum guidelines broken. I suggest you start a new post.

Hi Sttrotta,

Something like these.

/*============================================================================================================
Purpose       : Displays devices lists that are connected in a selected net or wire  in the schematic
                and higlights all its connection. It can be use for tracing connections in schematic.
Process       : Any process
Environment   : VXL schematic editor , this skill file can also be run in VXL layout editor.
How to run       : 1.Enter  in CIW. load("/home/marben/SKILL_VXL/net_selected.il")
                             2.Select a portion of net or wire in the schematic window, then move the cursor in the
                                CIW, then press 2 in the keyboard.
                             3.All devices connected to that net will be automatically displayed in a text file,
                                netConnection_layout.txt will be automatically created in user's VXl directory.
Function Name : net_selected()
