dbcreateParamInst??

C10,

Did you read the manual? There's a description of the arguments, what they mean, and an example.

If using IC61X you can run "cdnshelp" and search for dbCreateParamInst. In IC5141, you can use cdsdoc. If you have difficulty doing that, open <ICinstDir>/doc/skdfref/skdfref.pdf and search in there.

Regards,

Andrew.

Hi Carlton,

As Andrew has mentioned, the documentation should cover this.  Here is the entry from cdnshelp:

dbCreateParamInst( 
  d_cellView 
  d_master 
  t_name 
  l_point 
  t_orient 
  [ x_numInst 
  [ l_params 
  [ b_physOnly ] ] ]
) 
=> d_inst | nil 

Description

Creates a parameterized cell instance (of cellview d_master) in the cellview d_cellView with an origin and orientation specified by l_point and t_orient.

The values and types of the parameters for this instance may be optionally specified in l_params. Parameters not specified in l_params are defaulted to the ones defined in the master cellview d_master. Similarly, if l_params is not specified, the instance is created with the same parameters defined in its master.

Arguments

d_cellView
Cellview the instance is placed in.

d_master
Parameterized cell master cellview of the instance to create. 
This parameter must be a super master; use of a submaster can cause unexpected behavior.
The rest of the arguments are identical to those of dbCreateInst except l_params.

t_name
If specified, the instance is named by t_name; if nil the program assigns a unique name to the instance. t_name must obey the syntax of instance names as defined at the beginning of this chapter.

l_point
Origin of the new instance.

t_orient
Orientation of the new instance.

x_numInst
Number of instances; if t_name is given, it overrides any value specified by x_numInst (that is, the number of instances is derived from the name instead of taken from the x_numInst argument). If not specified, the default is one.

l_params
List of l_param, where l_param is list(t_propName t_propType g_value).

b_physOnly
Optional boolean argument that specifies whether the instance is only in physical domain when the argument is t; or it is in both physical and module domain when the argument is nil. Default is nil.

Value Returned

d_inst
The dbObject of the instance.
nil
The instance is not created.

Example

dbCreateParamInst(inCellView masterCV "inst1" list(0 0) "R0" 1 list(list("w"
"float" 2.0) list("l" "float" 5.0) t))

Hopefully the above is enough to get you started, if for some reason you cannot access the documentation.

Lawrence.

 Note that the parameter list is a list of lists in the format of ("paramName" "valueType" value ). If the value is a string, it should be in double quotes.

You have to open the cellView to get the masterCV. This is usually done in read mode. If the cellView is already opened, there is no performance issue in doing this:

masterCv = dbOpenCellViewByType( libId "cellName" "viewName" "viewType" "r")

Thanks,

   I cant access documentation...So i needed this explanation.Thanks everyone for the guidance...
