how to retrieve the hierarchy tree from a design

Derek WANG

Hi All

I am trying to right a skill script to record the hierarchy tree from a design, and also record the design version of every used instance view.

I have managed to do the second the part, but still struggle with the first one.

I have read the post from skillprogrammer and Andrew Bechkett

http://community.cadence.com/cadence_technology_forums/f/48/t/26647

The "CCSschTree.il" is a nice code, unfortunately, it is not what I want.

As in the output of "CCSschTree.il", the view type of every sub-blocks is "symbol"

this is reasonable, as the "symbol" of each sub-blocks is indeed used in the upper level schematic.

but on the other hand, this is not the cellview used for simulation.

In the GUI of cadence, the info I need is locates in the "config" cellview, and shown by the "Virtuoso Hierarchy Editor". mainly in the "View to Use" column.

I'd like to know, is there a good way to retrieve such info?


Thanks a lot.

  • Hi Yi,

    Both CCSschTree() and CCShdbSchTree() do this already if you pass the ?displaySwitchedView t argument. For example:

    CCShdbSchTree(?libName "opamp090" ?cellName "adc" ?viewName "config" ?displaySwitchedView t)
     gpdk090 resm2 symbol R0 [schematic]
       gpdk090 primRes2 symbol R0 [spectre]
     opamp090 adc_64comparators symbol ADC_64COMPARATORS [schematic]
       opamp090 adc_comparator_array_actr symbol I8 [schematic]
         gpdk090 resnsppoly symbol R16 [schematic]
           gpdk090 primRes3 symbol R0 [spectre]
         gpdk090 resnsppoly symbol R17 [schematic]
           gpdk090 primRes3 symbol R0 [spectre]
         gpdk090 resnsppoly symbol R18 [schematic]
           gpdk090 primRes3 symbol R0 [spectre]
         gpdk090 resnsppoly symbol R19 [schematic]
           gpdk090 primRes3 symbol R0 [spectre]
         gpdk090 resnsppoly symbol R20 [schematic]
           gpdk090 primRes3 symbol R0 [spectre]
         gpdk090 resnsppoly symbol R21 [schematic]

    Regards,

    Andrew.

  • Hi Andrew


    Thank you for the quick reply.

    I am sorry that I did not notice such characteristic of the CCSschTree() and CCShdbSchTree()

    it's really glad to know I can get the cellview of the simulation.

    I would continue my code based on CCSschTree() and CCShdbSchTree()

    Best Regards

    Yi
