How to assign user-defined netnames to the multiple nets drawn though rodcreatpath

Hi,

 I want to assign user-defined netnames to the nets that I draw. I can get the values through user with help of "Form", but how to assign them to the drawn nets. Can anyone help me on this.

;; Create a shielded path
procedure( shield()
errset(
(let (cv layer purpose list_draw_layer tech width1 tfId)
cv= geGetEditCellView()
layer = car(leGetEntryLayer()) ;displays layer on LSW is taken
purpose = cadr(leGetEntryLayer()); displays drawing or pin on the selected lsw
list_draw_layer =list(layer purpose)
tech = techGetTechFile(geGetWindowCellView()); rule deck file id is stored in tech
width1 = techGetSpacingRule(tech "minWidth" layer) ; the minimum width is stored in width1
rodCreatePath(
?name "shield"
?layer list( layer purpose )
?pts list(2:-15 2:-5 15:-5 15:-15)
?width .16
?justification "center"
?cvId cv
?offsetSubPath
list(
list(
?layer list( layer purpose )
?justification "left"
?sep .12
?width .08
) ;end of offset sublist1
list(
?layer list( layer purpose )
?justification "right"
?sep .12
?width .08
) ;end of offset sublist2
) ;end of offset list of lists
) ;end of rodCreatePath
) ; end of let
t
) ; end of errset
) ; end of procedure

The above mentioned programmes draw the net selected on the LSW Choice. Can anyone tell me, what i need to add in this programme so that i can assign the netname what user gives.

 

Regards,

Manu

     All parts of a multipart path can be assigned net information using the Rod Connectivity Arguments as described in the Virtuoso Relative Object Design User Guide. 

     For each of the objects and sub objects in your ROD code above add the keyed argument:

     ?net  "Net Name" ; Substitute the proper net name

    If the net does not exist it will be created.

     The rodCreatePath command is documented in the Virtuoso Relative Object Design User Guide so go there for more information on the other arguments. This is the minimum necessary:

    rodId = rodCreatePath(  ?layer "metal1" ?width 0.5 ?pts list({list_of_points}
                                       ?netName "net1"
                                       ?offsetSubPath list(
                                       list( ?layer "metal1" ?width .5 ?sep .4 ?justification right ?netName "gnd" )
                                       list( ?layer "metal1" ?width .5 ?sep .4 ?justification left ?netName "gnd" )
                                       )
             )
