Getting variable names from schematic view

artGetDesignVarList(cvId) will return a list of design variable-value pairs. This is actually the value of the "designVarList" on the cell (i.e. ddGetObj("libName" "cellName")~>designVarList ). There's no public API to set it, but it's just a matter of setting this property yourself.

 Hi Andrew,

Thanks for your help. However, it doesn't seem to work for me. Here are the outputs of the two things:

ddGetObj("mylib" "mycell")~>designVarList

nil

(although this cell has around 18 variables defined, which show up in Artist when I copy them from the cell view)
cv = asiGetCurrentSession()

stdobj@0x19a14024

artGetDesignVarList(cv)

Then I looked up the manual, and it seems that the correct function name is artGetCellViewDesignVarList

But even then it doesn't work.

 
cvid = asiGetTopCellView(cv)

db:0x15aae292

artGetCellViewDesignVarList(cvid)

nil

Am I doing something wrong?

Sorry, I jumped the gun here. This sequence of commands does seem to work.

 sv = (sevStartSession ?design nil ?lib "mylib" ?cell "mycell" ?view "schematic")
cv = asiGetCurrentSession()
sevCopyCellViewVariables(sv)
asiGetDesignVarList(cv)

However, the ddGetObj()->designVarList still doesn't seem to work, though that will be the preferred method to go.

Sorry, typo in my previous reply - it should have been artGetCellViewDesignVarList(). This is getting the variable names and values that have been saved back to the cellView with "Copy to cellView" (it actually copies them to the cell, rather than the cellView).

The sevCopyCellViewVariables will traverse the hierarchy and add those variables into an ADE session. artGetCellViewDesignVarList does not do any hierarchy traversal - there's no public API (as I said) which will do that other than sevCopyCellViewVariables. Presumably when it collects them, they do not have any values - the only values will be found by virtue of the value having been stored in the designVarList property on the cell object previously.

Regards,

Andrew.

Hey Andrew,
is there any way to select and read variables used in a schematic view thus I would not need to open an ADE window and/or have copied the design variables into the CDF file?

I do understand that I will not get values of the design variables but would like to use the design variable names to compile a stimuli/config file.

If there is no way to get design variable names from schematic directly I would be interested if there is a way to close the ADE window w/o the pop-up asking if I want to save it?

Thanks and best regards

Unfortunately the function to search the hierarchy to find any design variables used in expressions is private. There is the artGetCellViewDesignVarList which gets all the variables which have a value in the cell property bag, but that’s not going to find any that haven’t been “saved to cellView” before (it doesn’t really save to cellView; it saves to the cell).

Opening up an ADE session and then closing it again is going to be a bit hacky (and hard to get right).

I would suggest that you contact customer support asking for a public function to be made available. I’m not sure the current function is quite in the right state to be made public (the interface is a bit awkward), but it seems a reasonable request to have a public way of doing this.

That said, I can think of a non-graphical way of doing this using ADE Explorer/Assembler “mae” APIs:

; create a new maestro view
sess=maeOpenSetup("mylib" "ampTest" "maestroSearch")
; specify a fixed test name test1 and specify the lib/cell/view to search
maeCreateTest("test1" ?lib "mylib" ?cell "ampTest" ?view "config" ?simulator "spectre")
sdb=axlGetMainSetupDB(sess)
sevSess=axlGetToolSession(sess "test1")
; this is the public function normally used to populate the variables from the cellView
sevCopyCellViewVariables(sevSess)
test=axlGetTest(sdb "test1")
varNames=cadr(axlGetVars(test))
; could use maeGetVar to get the value of each variable if there is one?
varNamesValues=foreach(mapcar varName varNames list(varName maeGetVar(varName ?typeName "test" ?typeValue "test1")))
maeCloseSession()
; delete the temporary maestro view
ddDeleteObj(ddGetObj("mylib" "ampTest" "maestroSearch"))

It’s a little complicated, but it seems to work pretty well in my case - varNamesValues is then a list of lists of variable names and values (might only be an empty string if it’s never been set in ADE and saved to cellView).

Regards,

Andrew.
