Can you please tell me if it is possible to export LEF file from the
cells in current layout library in IC6.1.3? And if yes, how to do that or what
other alternatives to use?Because
it seems, that simple clicking on appropriate buttons don't give the desired/any
Thanks in Advance,
This ought to work. In order to find out what is going wrong, it would be useful to know:
I just tried it and it worked for me.
In reply to Andrew Beckett:
LEF File Name:abc.lef
"cells" buttom is highlited
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

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?
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.
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?
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.
