Exporting LEF format file from layout library

Hi Shushanik,

This ought to work. In order to find out what is going wrong, it would be useful to know:

1. What subversion of IC613 are you using (Help->About in the CIW will tell you this)
2. What "simple clicking" did you do - perhaps a picture of the filled in File->Export->LEF form would help
3. Were there any errors in the CIW (or CDS.log) when you OK'd the form?

I just tried it and it worked for me.

Andrew.

Hi Andrew,

1.  I am using IC6.1.3.500.10
2. This is what i do:

     File-Export-LEF

_____________________________________

LEF File Name:abc.lef

Library name:tsmc45

"cells" buttom is highlited

Output Cell:MUX2_8

Output Views:layout

Log File Name:abc.log

LEF version: 5.6

"Use GUI Fields" buttom is highlited 

__________________________________________ 

No Errors occur. At first, everything seems fine. But the problem is that the generated abc.lef file does not contain information about specified MACRO. It seems that it gives information about technology file. So, imported abstract view is empty.

MACRO MUX2_8
  PROPERTY oaTaper "__DerivedDefaultTaperCG" ;
  PROPERTY lastSavedExtractCounter 303 ;
END MUX2_8

Thanks,

Shushanik

 Pleaseeeee help me.This is realy very hot!!!!

Do i need the abstact views of cells before exporting them as .LEF format cells.Do i need some changes to made in technology file?

How to get comlete LEF file?

Thanks in Advance,

Shushanik 

If it is really hot, asking in a Community Forum is not the right place to do it. Go to Cadence Customer Support (http://support.cadence.com). The Community Forum is not a substitute for customer support - it is purely down to voluntary responses by the community (including a few of us from Cadence who do this in our spare time - for example, it is not part of my job to respond on these forums).

My guess is that the cellViews you are trying to export are just arbitrary layout. Normally you need to have pin information on the layout, and boundaries and blockages and so on - usually things that will either have been created by hand using a tool such as Virtuoso Layout Suite XL, or by using the abstract generator.

Hello Andrew, 

Thank you. I do appreciate that.

My layout design is complete and has pins,boundary....etc.

The only solution i can see at this point is to change technology file.Can it help?

Hi Shushanik,

I can't see why that should be necessary (changing teh technology file).

Best is to provide the data to Cadence Customer Support so they can take a look and find out why.

Regards,

Andrew.

 OK,thank you.
