A question regarding CCSchangeCells.il ?

Hello All,

I am having some problems running these scripts.

I am using CADENCE 5.41 with a UMC PDK kit and I want to use these scripts to change from one lib/view  to another.

Here is the conv.config file that I am using

(
  (nil
   fromLib   "UMC_18_CMOS"
   fromCell  "N_33_MM"
   toLib     "umc162ehv"
   toCell    "N_5V"
   CCSinvokeCdfCallbacks(cvId ?callInitProc t ?useInstCDF t)
   params (
           ("w" "w")
           ("l" "l" )     
           ("m" "m" )

           ("Nf" "fingers")
           )
   ) 
)

The transistos l and w change correctly but the number of fingers, width of fingers... are not correctly change.

Can someone help me with this issue?

Am I doing something wrong here?

I forgot to mention that I have tried also with this option:

abInvokeCdfCallbacks(cv ?callInitProc t ?useInstCDF t ?order list("w" "l" "fingers"))

ans some others that I have founf on your posts but it still does work properly.

 Your config file is wrong. It should be:

(
  (nil
   fromLib   "UMC_18_CMOS"
   fromCell  "N_33_MM"
   toLib     "umc162ehv"
   toCell    "N_5V"
   runCallbacks (?callInitProc t ?useInstCDF t)
   params (
           ("w" "w")
           ("l" "l" )     
           ("m" "m" )

           ("Nf" "fingers")
           )
   ) 
)

You can't just stick arbitrary function calls in there - the runCallbacks is a keyword to tell it to run abInvokeCdfCallbacks - and by specifying a list of arguments, it will call it with those arguments.

Thank you very much Andrew, now it is working fine and I can put all the different parameters that I have to translate from one technology to the other.

My idea is to do the same thing with the layout. I tried to use this script but it is not working. This scripts can only be use for schematics??

Is there any easy way to do layout translations from one technology to another?

Thanks a lot,

Maria

Hi Maria,

I think it should work with layouts (from a look at the code - I didn't actually try it). You'd have to call:

abConvertComponentParams("/the/path/to/config.file" geGetEditCellView() nil)

That last nil is important - otherwise it would try to do a "check" on the view at the end (and that's a schematic check). Apart from that, nothing jumped out at me as being a problem for layout.

Regards,

Andrew.

 Hi Andrew,

I tried to use it also with the the command (geGetEditCellView()) at the end like you said but in both ways it gives me a nil on the ciw and doesn´t do it. It doesn´t give me any error this is way I am not sure what the problem is.

 Do you know what the problem can be?

Best regards,

Maria

Maria,

You will need to set fromView and toView in the config file to be "layout". Otherwise it defaults to "symbol" and consequently it will try to convert all the symbols in your layout - of which there will be none!

Andrew.

Hello Andrew,

It worlked!! The components in the layout now are from the other technology. The only problem is that the place were it puts them is different. I think that there is a problem with the origin or the coordinates.

I will try to see how can I solve this,

Thanks again,

Maria
