modify netlist but don't change the schematic in skill function

Hi Zfeng,

Why not make the value a design variable and then use desVar() to change it before each run? Your requirement is not that clear to me though.

Changing the netlist absolutely should not be necessary.

You could, although you'll then need edit access to the schematic. Also you need to know the sources somehow anyway.

Knowing the available parameter names can be found easily enough by looking at the Tools->CDF->Edit CDF form.

 Hi,

    yes, you are right! i met a little trouble when i use my way to change the component CDF,  in the schematic composer i can do it correctly, but when i open the ADE, the problem truns up! i can't save the change any more by function schHiCheckAndSave(),

*WARNING* geGetEditCellView: Invalid graphics editor window.

*Error* schCheck: argument #1 should be a database object (type template = "d") - nil

so i think this is the reason why you said i need to edit access to shematic!

procedure(editVpulse( source new)
cvid=geGetEditCellView()
inst=dbFindAnyInstByName(cvid source)
oldValue=inst->v1
inst->v1=new

schHiCheckAndSave() ;; these two lines can work well only when the composer window(or shematic window is the currentWindow)

hiRedraw()

)

 i intend to run the procedure totally in background, it's inconvenient if user have to push the "save and check" button in shematic window. how can we use the schHiCheckAndSave() when the shematic window is not the currentWindow?

thanks,

my idea:

i mean that the shematic window is the current design window, and we need simulate it in some condition such as the vpulse v1=3  v2=3 (like a constant vdc) at the beginning but later v1 need to be fixed at v1=0 in the transient paramAnalysis. so for the first step we want to collect some information(VoutMaxmum) in background before the paramAnalysis

Use schCheck(cvId) and then dbSave(cvId) rather than the interactive function which assumes that the schematic window is current.

Similarly you are calling geGetEditCellView - you had a different question about that, so I'll answer that there.

I still think this is a pretty horrible way of doing this.

 Hi,

   yes, you are right. there is  a veriloga model which named pd in my schematic. and the model has some parameters like "P0". i am trying to get the value of this parameter, i can see there is a CDF parameter of view field in the form when i select the pd and push the "Q" button for editing the properties. i want to use the following procedure to get the parameter "P0" value

procedure(zfSearchInstance( source ) ;source can be replaced by any instance you want to select ,eg "pd" in this application widSchImager=sevOpenSchematic(sevSession(widTriggerSimulatorWindow))
cvidImager=geGetEditCellView(widSchImager)
inst=dbFindAnyInstByName(cvidImager source)

; here i want to select the pd and get the field value of P0 in pd model

paramView->value = "veriloga"
param=P0->value

;i don't know how to write the above code exactly

schCheck(cvidImager)
dbSave(cvidImager)
)

welcome to your suggestion in anyway.

Regars,

zfeng

There is no need to alter the "CDF Tool Filter" setting - that's only for the edit properties form to filter which properties are shown.

If you want to get the value, simply do:

inst~>P0

or to set it:

inst~>P0="new Value"

Andrew.
