Skill command to create the cell view?

Clearly you didn't do much searching or looking for examples, because this information should be pretty easy to find.

All you need to do is:

cv=dbOpenCellViewByType(libName cellName viewName "schematic" "a") ; fifth arg could be "a" or "w"

The mode is either "a" (append/edit) or "w". For a new view, it doesn't matter - but for an existing view, "w" will overwrite, whereas "a" will start from what's there already. The fourth argument is the viewType (not the view name).

Hopefully that will be enough for you to find the right part of the documentation, and some examples (e.g. on these forums).

Yes, that would work.

A slightly more portable way (which would work in IC5141 and IC61X/ICADV12.X) would be to use:

techBindTechFile(ddGetObj("myLib") "theTechLib" techGetDefaultTechName()) ; may want to add t as fourth argument

The techGetDefaultTechName will return the correct database filename in CDB or OA. Unlikely to change in future, but might as well future-proof your code.

Hi Andrew,

I have created a instance after creating a library and cell view using the following code :

library_name = "test_lib"
lib_id = dbCreateLib(library_name)
cell_name = "test_cell_1"
cv=dbOpenCellViewByType(lib_id cell_name "schematic" "schematic" "w")
techBindTechFile(ddGetObj(library_name) "tsmcN65" techGetDefaultTechName() t)
masterId=dbOpenCellViewByType("tsmcN65" "nch" "symbol")
dbCreateInst(cv masterId "M0" list(0,0) "R0" 1)

now I want to change the properties of that instance such as length and width and I am able to do that using following :

inst=dbFindAnyInstByName(cv "M0")

schReplaceProperty( inst_temp "l"  "len" )

schReplaceProperty( inst_temp "w"  "len" )

But the problem is that toltal_width and other parameters are not changing according to the above changed parameters.

That's because these are (probably) set by a CDF callback, and CDF callbacks are normally only called by form interactions, not database interactions.

Search on support.cadence.com for CCSinvokeCdfCallbacks or on these forums (using the search in the top right corner) for abInvokeCdfCallbacks - you should find a function to call the callbacks procedurally.

BTW, you don't really need to use schReplaceProperty - you can use dbReplaceProp or even just use inst~>w=len. You could also avoid using inst=dbFindAnyInstByName by just using the return value of dbCreateInst in the first place (this will be the instance id of the newly created instance).

Andrew

I'm not entirely sure what you're asking here. When you are interacting with the edit properties form, it will both change the property on the instance (at the database level) and then look at the callback attribute of the CDF parameter "l" for the cell that you're editing an instance of. abInvokeCdfCallbacks/CCSinvokeCdfCallbacks is a simplified interface to allow you to call those callbacks (by finding the function in the CDF, setting up the CDF appropriately and then calling the function). I suggest you use that rather than reinvent the wheel.

Regards,

Andrew
