Changing amount of rows and columns in a selected contact cell

Brian,
Take a look at the prop~>name values. You are incrementing every property by one. Since there are both row and column properties, you will therefore increment both. It is also possible that there are other properties that are not integers and will cause your code to fail. You can actually increment the value of the row and column settings by directly accessing the property by name.

fig~>row =  fig~>row + 1  (assuming row is the property name)

Also, in your code you are getting the prop value using:

car(fig~>prop~>value)

You are using "car" because fig~>prop is a list and therfore fig~>prop~>value is a list. However, you are incrementing ALL props with this since fig~>prop is a list:

fig~>prop~>value = propValue + 1

If you just want to change the first prop:

car(fig~>prop~>value) = propValue + 1

This is more consistent with the way you retrieved the value in the first place. However, the property list is not always going to be in the order you expect. You should look at the property name before you adjust the value either by going to the known property directly as I demonstrated (fig~>row), or by checking the name like this:

foreach(prop fig~>prop
  when(fig~>prop~>name=="row"
    fig~>prop~>value = fig~>prop~>value + 1
  )
)

Or you could use dbFindProp or dbGetPropByName instead of that last foreach:

prop=dbFindProp(fig "row")
prop~>value=prop~>value+1

Thanks lads, that did the trick. I appreciate the help!

hello guys,

can we use the car(.....) function on the left hand side...

ex: 

car(fig~>prop~>value)=propvalue+1;

is it possible?

i think not...

if it is impossible to use car(....) on the left hand side how can we modify only rows in that?

 hey try this

 procedure(viarowincrement()
fig=geGetSelSet()
foreach(fig geGetSelSet()
when(fig~>objType=="inst"
rov=fig~>row
fig~>row=rov+1
);when
);foreach
);procedure
hiSetBindKey("Layout" "Alt Shift<key>=" "viarowincrement()")

procedure(viarowdecrement()
fig=geGetSelSet()
foreach(fig geGetSelSet()
when(fig~>objType=="inst"
rov=fig~>row
if(rov>2
fig~>row=rov-1
);if
);when
);foreach
);procedure
hiSetBindKey("Layout" "Alt Shift<key>-" "viarowdecrement()")



procedure(viacolumnincrement()
fig=geGetSelSet()
foreach(fig geGetSelSet()
when(fig~>objType=="inst"
colum=fig~>column
fig~>column=colum+1
);when
);foreach
);procedure
hiSetBindKey("Layout" "Ctrl Shift<key>=" "viacolumnincrement()")

procedure(viacolumndecrement()
fig=geGetSelSet()
foreach(fig geGetSelSet()
when(fig~>objType=="inst"
colum=fig~>column
if(colum>2
fig~>column=colum-1
);if
);when
);foreach
);procedure
hiSetBindKey("Layout" "Ctrl Shift<key>-" "viacolumndecrement()")

Heres the code I ended up using. I noticed I had to delete the property once values had reached below 2 columns as it output strange behaviour for negative row and column values..

Hi to all, great job but I dont know what cadence version was used but in version 6

is not working....

it gives back this message:

BSchangeViaHorizDec()
(db:0x17910412)

 and nothing happen to the via.

keep up with the good feature.

Vasco

Vasco,

Looking at the code, it was written for IC5141 (or earlier) - essentially it follows the CDB model for vias (which are just instances). In OpenAccess, vias are separate objects - and the code checks that they are instances. It's not as simple as checking that the selected objects are vias - the property names are different, and the dbFindProp would fail. Needs a fairly hefty overhaul (don't have time to do this myself, unfortunately).

Andrew.

Hi, thanks for the reply...

I see, update changes... anyway I didn't need a so complex code, just a way to input variables in the a field inside the option form.

 But thanks for the help anyway, maybe some other time.

best regards and keep up with the good work

Vasco
