Hierarchically Layer generation

Hi Subhabrata

Thank you very much for posting this new thread.

Currently the script only generates the layers at the top level. If it is necessary to generate the layers at the subcell level, it might be good to create a foreach loop for those cells. E.g.

lib="myLib"
cellList=list("cell1" "cell2" "cell3" ... " cell99")
foreach( cell cellList)
   cv=dbOpenCellViewByType(lib cell "layout" "" "a")
   CCShierLayerOps(?cv cv "inputLay1" "inputlay2"  "outputLay" "AND" 0 ?level 32)
   dbSave(cv)
   dbClose(cv)
) ;foreach

Hi Quek,

thanks for the solution. I got the logic behind, where I can provide the library and cell details and one by one it will peak the cell to do the selected operation. I need to try with this option also.

But, I want to make it in other way,

Once I have opened a top cell, i want to get the layer generation only for the cells inside that hierarchy, and the generated layers should be placed in each different hierarchy cells in place of adding it only at the top level.

Logically, the way it is reading all the hierarchies from the input layout, I want the new layers also should be added to the individual cells inside the hierarchy from the top cell I have started the script execution.

Please check it once and let me know if the requirement description creates any other queries.

Thanks for your support.

Hi Subhabrata

I think you need the following:

a. Use a procedure to go through the hierarchy recursively from the top layout and gather the names of the subcells
b. Use the previous method to open each of the subcell cellview and generate the layers in it

This should be able to solve your problem.

Hi Quek,

It could be better if we have the option in the GUI, where I will be having the other operations (Input Output layers, Boolean operations or Grow By option etc ) to select, as well turning ON/OFF a check box will be able to take care about the hierarchical Cell specific placement of generated layers or only at the top level placement of the generated layers.

And this way we can use generalize the script. Please check it once and let me know.

Thanks & Regards,

Hi Subhabrata

Actually it would be best for you to modify the script to fit your specific requirements.

Hi Subhabrata/Quek

Could anyone of you please post the link for CCShiHierLayerOps.il solution?

Thanks

Thanks, Quek.

Actually making it for hierarchical generation, may not be the specific requirement.

To pass the Hierarchical LVS, it is required to add the layers in different level of the hierarchy.

It will be really helpful, if you can add the option.

Thank you,

Thanks Quek.

Hi Quek,

Can you please provide the details, how we can use it with the Create Layer GUI and where we can update the CCShiHierLayerOps.il script regarding that?
Actually, with the CCShiHierLayerOps.il script, it is creating a new layout reference and flattering all the hierarchical instances in one level.

I was trying to disable that and call the instances every time to create the new layer immediately in the hierarchy.

Please put your comments and suggest referring the CCShiHierLayerOps.il script.

Thank you,
