Via Doubler

Guest
Hi all,

I have a request from my layout group to come up with a quicker way to
double a via on a route. Basically, we are routing with the path
command and with wires not wide enough for two vias one is placed at
transitions.

Currently, the user is selecting the via to double and using
leHiEditProp(), filling out the form to grow the Row or the Column of
the via and hitting apply.

I would like to have some code where the user selects a via and could
"toggle" a double cut via by pressing alt v. Double row if user hits
the alt v once and and "toggle" to double column if alt v is hit
twice.

I have written widgets to manipulate forms with skill in cadence but
the form that comes up with leHiEditProp() doesn't seem to work that
way :)

Any ideas or sharing of code that does similar to this would be
appreciated!!

Thanks,
Eric

This would set the rows to be 2 for all the selected vias. Use ~>column for columns.

foreach(selObj geGetSelSet()
when(leIsContact(selObj)
selObj~>row=2
)
)

This is for IC5141 (which I assume you're using). It's a bit more complicated in
IC61, because vias a separate objects, and it probably would need the via master
changing (don't have time to check right now).

Andrew,

I attached the code that you gave me with a slight change to increment
and decrement the via selectic. I bound this to
the wheel on the mouse. The user can select the existing via and add
to the row or column. It stops if the
decrement of the row or column is at a count of 1.

Thank you for your help and if you see something wrong let me know!
Eric

I ended up with the code below. If a user selects an existing via,
the user then can use the "roll" on the mouse to add and subtract rows
and columns.

Thank you Andrew for your help!

By the way, Eric, you could make these a bit simpler:

procedure(RowAddRoll(incr)
foreach(selObj geGetSelSet()
when(leIsContact(selObj)
selObj~>row=max((selObj~>row||1)+incr 1)
)
)
)
procedure(ColumnAddRoll(incr)
foreach(selObj geGetSelSet()
when(leIsContact(selObj)
selObj~>column=max((selObj~>column||1)+incr 1)
)
)
)

hiSetBindKeys( "Layout" list(
list("Shift Alt<Btn4Down>" "RowAddRoll(1)");
list("Shift Alt<Btn5Down>" "RowAddRoll(-1)");
list("Ctrl Alt<Btn4Down>" "ColumnAddRoll(1)");
list("Ctrl Alt<Btn5Down>" "ColumnAddRoll(-1)");
))

Note that your parentheses were in the wrong place in your functions - the
second foreach loop was actually nested within the other one. I'm sure you
didn't mean to do that...

I essentially changed it to do selObj~>row||1 to handle the case where the row
property was nil - it will be either the row property if it's there, or 1
otherwise. And then the max() takes care of it going below 1 when you're
decrementing (incr is -1).

BTW, I didn't test any of this - it's just a casual observation!

Regards,

Andrew.

Andrew,

I am new to skill, have some programming training from college many
moons ago and really appreciate your
inputs. I am working in a small group and have been asked to pick up
Skill code changes.

I have tried this code and it works perfectly.

Your Skill skills are legendary.

Thank you,
Eric

Eric,

No problem, and thanks for the compliment. One thing I meant to mention before
is that it's good practice to give your functions a unique prefix (which should
begin with a capital letter for customer functions) to minimize the chance of
clashing with anyone else's function that happens to be called the same thing.
So call them things like EDFcolumnAddRoll and EDFrowAddRoll (I just used your
initials), or something like that.

You may well be doing this internally, but it's good practice, in case anyone
else hasn't picked up on this (I think it talks about it in the SKILL
documentation).

Regards,

Andrew.
