report list with model name devices used in schematic

Hi Mauro,

Commonly in most PDKs the model name would be in a CDF parameter called model. So you can probably do:

cv~>instances~>model

to list all the model parameters (some may be nil because of being pins, or not having a model parameter, but you can start from there). Or if you have an individual instance object, inst~>model should return it.

Hi Andrew thanks for your quick answer. I'm using the code attached from cadence support web site. Can you help me to understand where put the line you give me. Sorry but I'm not so confident with skill code

Hi Mauro,

Despite having written that code (9 years ago), it's not a trivial task to change it to truly report the models. If the models are fixed for each device (i.e. you can't change them on a per-instance basis for the same component), then changing the bit that is in CCFleafCellCount.il  in the function CCFleafCellCount where there's a comment  Report each stopping cell  to this:

    ;--------------------------------------------------------------------
    ; Report each stopping cell, and sum up the total number of
    ; stopping cells
    ;--------------------------------------------------------------------
    (setq stoppingCellTable (getq obj stoppingCellTable))
    (let (cdf model)
      (foreach stoppingCell 
               (sort (getq stoppingCellTable ?) 'CCSleafCellCompare)
               (setq count (arrayref stoppingCellTable stoppingCell))
               (setq total (plus total count))
               ;---------------------------------------------------------
               ; Try to get the model from the cell CDF
               ;---------------------------------------------------------
               (setq cdf 
                     (cdfGetCellCDF 
                       (ddGetObj 
                          (car stoppingCell)
                          (cadr stoppingCell)
                          )))
               (setq model nil)
               (when cdf
                 (setq model (getq (cdfFindParamByName cdf "model") value))
                 )
               (unless model
                 (setq model "")
                 )
               (unless (or (zerop count) (null port))
                 (fprintf port "%s %s %s (%s): %d\n"
                          (car stoppingCell)
                          (cadr stoppingCell)
                          (caddr stoppingCell)
                          model
                          count
                          )
                 )
               )
      )

This then outputs something like this:

analogLib cap symbol (): 88
gpdk090 mimcap symbol (gpdk090_mimcap): 4
gpdk090 nmos1v symbol (gpdk090_nmos1v): 38
gpdk090 nmos2v symbol (gpdk090_nmos2v): 106
gpdk090 nmoscap2v3 symbol (gpdk090_nmoscap2v): 1
gpdk090 pmos1v symbol (gpdk090_pmos1v): 32
gpdk090 pmos2v symbol (gpdk090_pmos2v): 8
gpdk090 pmoscap2v symbol (gpdk090_pmoscap2v): 3
gpdk090 primRes2 symbol (): 1
gpdk090 primRes3 symbol (): 982
Total: 1263

As  you can see, it puts the model name in parentheses (if there is a model) after the component name. I'm afraid I don't have the bandwidth to try to make this more universal (i.e. try to figure out if it really is called model, or if the same component exists on the schematic with different values of model). Sorry! Maybe the above is enough though?

Regards,

Andrew.

Hi Andrew,

thanks a lot !! The code works as you  said when the same component is placed with two different models value only one is reported. I can work on this code and try to do fix this behaviour

Since many PDKs have a fixed model per component, I didn't want to over-engineer the solution if the quick change I made was sufficient. Sorry that I don't have the bandwidth to make a more comprehensive change to do what you want...

Andrew.
