A question regarding CCSchangeCells.il ?

 Hai! I found a code which will change cells from one lib/view to another.. in cadence sourcelink ...

I am using cadence IC6X version.. and a IBM(90nm) PDK kit ..

The code is working fine when I tried to convert cells from 'analogLib' to  'gpdk090'..

But when I tried this code in changing cells from 'analogLib' to  'IBM' models it's not happening..

I thought this is because of the following reason.. the IBM PDK kit defines the following params for w(width), l(length), m(multiplier) as

wf(string type),(wff float type), lf(string type), (lfffloat type) and  mpl(int type)...

The params w, l, and m assigned as user defined params after running the code..

I tried to assign the w, l, and m values to the wf, lf and mpl ... the form displaying the values correctly(in schematic).. but when I attempt generate from source it is picking the transistors of default values but the form values remains unchanged.. (in the layout)..

I hope the problem is understandable.... If not I will provide some more information...

Can please some one guide me to achieve this............

     Hi, Mr. Andrew,

                              I really very thankful to your kind response... I tried your updated code, it is working fine when changing cells of  'analogLib' to 'gpdk090' ... I don't know what's the problem with IBM PDK kit... After some trials atlast I got the solution ... it may not be that much efficient code as you have written... But this is a possible solution for me.......

    For every cell of analogLib, I am storing the respective (w, l, m, xy, orient) params and then I have created an instance of IBM model in that place by assigning the stored params( to the respective cell attributes) & then deleting the old one...

    And finally, I am running your code  like this " abInvokeInstCdfCallbacks(geGetEditCellView()) " ... And my custom gen4msource.il code is doing its job perfectly........

    Thank you very much once again............
