Can't retain the create->probe option across sch designs in tabs

ssram

I wrote the following code to open the selected instances in layout/schematic in a new tab.

But somehow this doesn't workout well since the create->probe doesn't work well in schematic across the tabs, also it gives the following ERROR. Could someone help me here to fix this?

*Error* _schIsUserEditable: argument #1 should be a string (type template = "t") - nil

;+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

procedure(srOpenLayoutInTab()

techLibName = techGetTechFile(geGetEditCellView())~>libName
myCells = geGetSelSet()

if( myCells then

foreach( cells myCells
cellViewType = cells~>master~>cellViewType
when(
cellViewType == "maskLayout"
if( cells~>isAnyInst then
myLibName = cells~>libName
myCellName = cells~>cellName
myViewName = cells~>viewName
printf("\nOpening the design %A from lib %A in a new tab\n\n" myCellName myLibName)
window = hiOpenWindow(?session hiGetSessionWindow(hiGetCurrentWindow()) ?type "graphics" ?appType hiGetAppType(hiGetCurrentWindow()))
window->sessionWindow=hiGetSessionWindow(hiGetCurrentWindow())
geOpen(
?window window
?lib myLibName
?cell myCellName
?view myViewName
?viewType cellViewType
?mode "r"
)
);if
);when
);foreach

foreach( cells myCells
cellViewType = cells~>cellView~>cellViewType
when(
cellViewType == "schematic"
if( cells~>isAnyInst then
myLibName = cells~>libName
myCellName = cells~>cellName
;myViewName = cells~>viewName
printf("\nOpening the design %A from lib %A in a new tab\n\n" myCellName myLibName)
window = hiOpenWindow(?session hiGetSessionWindow(hiGetCurrentWindow()) ?type "graphics" ?appType hiGetAppType(hiGetCurrentWindow()))
window->sessionWindow=hiGetSessionWindow(hiGetCurrentWindow())
geOpen(
?window window
?lib myLibName
?cell myCellName
?view "schematic"
?viewType cellViewType
?mode "r"
)
);if
);when
);foreach

else
printf("\nNo instances are selected to open \n\n")
);if

);procedure

    Your code actually just opens the selected instances in a new tab, it does not really do a descend. If you compare the resulting tabs, you will notice that eg. the title bar for a real descend is "<instance name>(<cell name>)" (while your's should only show "<cell name>") and that the navigator has the hierarchy of the original cell with the treeview set to the descended subcell, and with that also inheriting the probes.

    Unfortunately I cannot tell what exactly has to be done after the open command to achieve this, but there is a solution, which almost does what you want.

    CCSschDescendWithUserControls

    It basically calls the builtin descend but initializes the values of the descend window, thus it does not open. You just would need to write a loop that modifies the current selection to select the wished instances one by one and call the core part with the hiEnqueueCmd and schHiDescendRead. You would however need to decide how to handle bus instances. Also make sure to skip pcells (e.g. ... && !cells~>master~>superMaster).

    As said, you are opening your design hierarchy in new tabs instead of descending the hierarchy, which will retain the net highlighting among other things. The "CCSschDescendWithUserControls" shared below solves a good problem but has some limitations as far as your issue is concerned, especially when iterating through multiple instances. I have written the following code for you, it's on my git repo, I have tested it on a schematic design however I don't have any layouts to test at the moment. The script is well documented,

    FTTdescend.il

    Cheers,

    Thanks a lot Riad, appreciate your help.

    The schematic descend works fine for me, but the layout portion doesn't seem to work well. I'm not sure if the envSetVal for layout is working well.

    The layout opens in the same tab of the window, it doesn't look like it honors the envSetVal.

    I tried the following in the CIW and i get some warnings.

    +++++++++++++

    envSetVal("layout" "descendCanvasType" 'string "new tab")
    *WARNING* envSetVal: type mismatch for variable 'descendCanvasType'
    in tool[.partition] 'layout'.
    nil

    +++++++++++++

    Thanks

    Found the issue... it was the way i was doing the envSetVal for layout. Instead of string, i should be using cyclic as below

    envSetVal("layout" "descendCanvasType" 'cyclic "new tab")

    Now the code works like a charm :-)

    Thanks Riad once again.
