Cadence stream-In layermap

Hi...
I am trying to copy the layer using stream-map file,but the cadence is
ignoring the other line in stream-map file.

Eg:
In GDS there a layer with stream number 15 datatype 0
In stream file I have given as
M8 dg 15 0
MX dg 15 0

But the cadence is importing only M8 and its ignoring MX.So is there
any option I need to set for importing the MX?

 

So you want to copy layer MX to layer M8 on StreamIn?
If that is the case you'll need to know what the layer number and
datatype is for MX then create a custom stream map file with this
info.

M8 dg 15 0
M8 dg ?? 0, (the ?? being the layer number for MX )

 

Thanks for your reply...
The option u have told will work only for StreamOut,But I want know
the same
option while importing.

Let me clarify my qustion:
In the GDS only one layer is exists ie layer no 15 datatype is 0.
After the import in cadence ,the result should be M8(As it is of 15
0 ) as well as M9/MX (This is the copy of M8 ).
So let me know the option I need to setup or eg: of layermap.

Thanks in advance.

This is described in the "Design Data Translator's Reference Manual", Chapter 2,
"Preparing to Use Stream and CIF Translators". The PDF is at
<ICinstDir>/doc/transref/transref.pdf . It says:

Same Stream Number and Data Type Pair Mapped to Multiple Layer-Purpose Pairs
----------------------------------------------------------------------------
In either the layer name map or technology file, the same Stream layer number
and data type pair might be mapped to more than one Design Framework II
layer-purpose pairs. In this scenario, Stream In translates all the entries for
that Stream layer only to the first Design Framework II layer-purpose pair
specified in the layer map or technology file.

thanks ..
But its not working for me ,what might be the problem?
I am able to Import only one layer. The eg: of layermap file I have
shown in first message.

That's what the documentation says it will do! If the same layer/datatype pair
is mapped to more than one DFII layer-purpose pair, it will only import onto the
first it finds, not all of them.

So it is working as documented. The problem is that what is documented is not
what you want, I guess ;-<

you are right..
Is there any other solution for this.

Copy the data from one layer to another (in SKILL, say) after you've imported
the cells?
