Help on creating via at specified points

Why not use leCreateContact(...) rather than trying to interact with an interactive form using hiRegTimer (which seems an awkward way to do it to me). If there's a procedural interface rather than a human interface version of a function, it's much easier to use that from a program...

Also, using prBoundary to do this is a bit of an odd use model, I'd say...

 hi Andrew,

                I did as you suggested in last post and I got it. I need to change layer encloser in Contact.

 hi All,

        I have a code for changing x,y enclosure for contact. But it doesnot work's properly. Iam using the version 5141. 

Code is below:

   tcDeclareDevice( "symbolic" "syEnhContact" "M2_M1c"

    ( (viaLayer "VIA1") (viaLayer2 "VIA1") (encByVia 0.05)

      (layer1 "MET1") (layer1Implant "") (layer1ImpEnc 0.0)

      (layer2 "MET2") (layer2Implant "") (layer2ImpEnc 0.0)

      (encByLayer1 0.3) (encByLayer2 0.2)

      (layer1XEnc 0.1) (layer1YEnc 0.2)

      (layer2XEnc 0.0) (layer2YEnc 0.4))

    ( (w 0.6) (l 0.6) (row 1) (column 2) (xPitch 1.2) (yPitch 1.2)

      (offset 0.0) (side "center") (layer1Dir "x") (layer2Dir "x")

      (xBias "center") (yBias "center")

      (leakLength 0.0) (areaPin ""))

)

Then CIW shows :

 *WARNING* No techfile specified - or must be called within technology file load.

 <<< Stack Trace >>>

 tcDeclareDevice("symbolic" "syEnhContact" "M2_M1c" ((viaLayer "VIA1") (viaLayer2 "VIA1") (encByVia 0.05) (layer1 "MET1") (layer1Implant "") ... ) ((w 0.6) (l 0.6) (row 1) (column 2) (xPitch 1.2) ... ))

 load("venu1/EnclosureContact.il")

 *WARNING* Failed to create device header.

*Error* techGetDeviceClass: argument #1 should be a database object (type template = "dgt") - nil

What's the problem

 hi Andrew,

                 I write following code for creating contact array at specified boundary.

 
procedure(contact1()
enterBox(
?prompts list("Enter the first corner of your box."
"Enter the last corner of your box.")
 ?points         nil
 ?doneProc "contact"
 ?alwaysMap t
))
procedure(contact(w done points)
v=points
cv = geGetEditCellView()
y1=car(reverse(car(reverse(v))))
y2=car(reverse(car(v)))
x1=caar(reverse(v))
x2=caar(v)
dx=x1-x2
dy=y1-y2
mx=x2+(x1-x2)/2
my=y2+(y1-y2)/2
no.columns=round((dx-.12)/.54)
no.rows=round((dy-0.12)/.54)
overlapx=dx-(no.columns-1)*0.54-.26

leCreateContact(
cv
 "M2_M1c"
 mx:my
 "R0"
 1
 1
 no.rows
 no.columns
 0
 0
 "center"
   "center"
)
)

hiSetBindKey("Layout" "Shift<key>n" "contact1()")

But i want to create whole area in specified boundary will be filled by automatically adjusting the layers enclosure on contacts. Layer's enclosure on contact's is varied automatically for filling whole area specified in boundary.

The problem is that the enclosures are class parameters, which means that they are common to all instances of the contact. To get around this you'd probably need to declare your own syEnhContact device (see <ICinstDir>/tools/dfII/samples/techfile/syEnhContact.tf as an example, although it doesn't address this particular problem) which had additional formal parameters which allowed you to override the enclosures. You might be able to do this with cdsVia devices too (I'm not sure though and don't have an example to try).

It's certainly doable in IC61 with stdVia devices even, but in IC5141 the built-in vias are more limited.

Andrew.

 hi Andrew,

               I still need this. Do you have any idea or example codes for this topic. Iam using the version 5141.

I did give some ideas in my previous post.

Here's a bit more detail though (I did a quick experiment). If you look at <IC5141instDir>/tools/dfII/samples/techfile/sample2003.tf it shows a couple of cdsViaDevice definitions (e.g. the one for M1_M2).

If you define a via like this, you can then do:

inst=car(geGetSelSet())
inst~>layer1XEnclosure=0.3
inst~>layer1YEnclosure=0.5
inst~>layer1Direction="btrl"

the direction can be any combination of the letters b (bottom), t (top), l (left), r (right) which indicates which sides the enclosure should be applied on. There are also the layer2 equivalent properties.

I think that does exactly what you want.

Note that the sample2003.tf tech file contains some OA-specific entries which will cause warnings if you load it (e.g the standardViaDefs and customViaDefs), but you can certainly borrow the ideas from this.

cdsViaDevice is documented in the documentation too - just search for cdsViaDevice. In particular you can see this in the doc/ascitechfile/ascitechfile.pdf and doc/vlehelp/vlehelp.pdf

Andrew.

  Thank you Andrew for replay. My process had some contacts(M1_POLY) is defined with symcontactdevice and  some contacts(M1_M2) with cdsviadevice. As you said, That code works for cdsviadevice class. Is there any way to set symcontactdevice ?  Or how can i create cdsviadevice.

I've already said that this can't be done with normal vias (e.g. symContactDevice) because the parameters are class parameters, not instance parameters. I've also explained how this can be done with a cdsVia, and have pointed you both at an example and also where in the documentation it explains how to create these in the tech file.

It's unclear to me what more information I could provide that I have not already provided. Did you take a look and try the example, and did you read the documentation?

Regards,

Andrew.
