  • dbCreateVia() questions: justification and other examples

    I am migrating my pcells to IC6, and I am wrestling with the new via model. Our PDK uses "standard vias", so I understand that I need to use the dbCreateVia function. Apparently, I can override paramaters, even for standard vias, so I can use the following syntax: dbCreateVia(cvId viaId list...

  • Re: ESD instances list .

    Hi Marbs, This sounds similar to my recent post on finding certain schematic instances , take a look. To help I will repeat the SKILL code snippet here. cv = geGetEditCellView() => db:0x452bdf92 esdCells = setof(inst cv~>instances rexMatchp("^[eE][sS][dD]" inst~>cellName)) => (db...

  • Re: methods for variable integer to string conversion

    Thanks Andrew for your suggestions. I like the array idea too. However, it would be nice to be able to use a wild card so that I don't have to declare all the variables in the array. e.g. I thought declare(pp**_[10]) would let me declare the array just once for something like: pp1x_[m], pp1y_[m]...

  • Re: methods for variable integer to string conversion

    Hi Lawrence, I shall appreciate if you could help me achieve the opposite, i.e. converting string to a variable. I want the vertices of a polygon to be variables with an index (say 'm') included in its name which gets updated in a 'for' loop. I'm unable to assign an integer value...

  • Re: Auto contact SKILL function

    Hi Yaosan, Yes, the code just transforms the bounding box, not the shapes themselves. If I have understood your problem correctly, you are wanting to create a via at the intersection of two appropriately overlapping shapes in the layout, whether these shapes are present at level 0, or at other levels...

  • Re: Auto contact SKILL function

    Hi again Yaosan, I just searched and found Solution 11185634 Additionally there is a solution which uses dbGetOverlaps which may help: Solution 11304230 Hopefully this will help you. Regards, Lawrence.

  • Re: Auto contact SKILL function

    Hi Yaosan, First, I will assume that you are talking about version IC61x, since the menu you described was "Create Via" and not Create Contact. In IC61 (based on the Open Access database), vias are objects as opposed to instances (as they were in IC5141 and earlier), so you would use the dbCreateVia...

  • Re: Tcl programs in virtuoso

    Hi Bharath, Yes, it is possible for the SKILL-based DFII session to interact with an external script or program; perhaps the easiest method is to use Inter-Process Communication. The SKILL functions for this begin with the prefix of ipc , such as ipcBeginProcess() for starting the external script or...

  • SKILL GUI

    Hi, I want to do a simple GUI with call backs for a transformer which I've coded. Any idea where to start from? If anyone has the manual for doing GUI's, then please forward it to me. Many Thanks, Adil Khalil.
