How to get an instantiated cellview in CDF |
|
|
I create a pcell with SKILL. Now I want to know the orient of the instantiated cell in its CDF callbacks,
so I must first get the ID of the instance. But how?

If you are placing an instance rather than editing one, then there is
not yet an instance at all. which instance do you want to
get in this case in your CDF callback?

When I am creating one instance, the ID must be nil and I can simply use the default orientation.
Then if I edit the parameter of the cell, I need to know the ID of the instance.

Wat do you want ot do with the orientation in the CDF callback?

Just for display.
I shall give a description of my pcell. It is a MOS capacitor array include two of the following parameters: col and row. The two parameters' CDF prompts are Columns and Rows separately. While an instance is placed with a rotation of 90 degree, Columns becomes Rows and Rows becomes Columns. It seems that the prompt of a CDF parameter is not allowed to be changed, so I set up a pair of shadow parameters: col_r and row_r. They should be displayed olny when the instance has a rotation (R90 R270 MXR90 MYR90) and their corresponding promts are Columns and Rows, while the first two parameters are made to appear only when the instance without any rotation. The value of these parameters are synchronized with callbacks but the instance ID is needed to determine its orientation.
My intention is simply to make my pcell a little more perfect.

geGetSelSet( ) returns a list of dbId's of selected sets including
instances.
But that's the point form my perspective, what about if
the user selects two ore more instances of the PCell and want to modify
the parameter for all together (this is possible in the edit prop
form with the Common option)???
Then you need to process more than one instance dbId's, in a CDF callback
.... hmm?
In my opinion a user should be smart enough to know if the orientation is 90^
that rows are columns etc..

And also the original question that Jim asked - before you create an instance,
there is no instance yet; the default orientation is not going to be valid if
you're choosing to place it rotated. I personally think it would be very
confusing to have the rows and columns keep changing... especially if it didn't
do it consistently.
