Encounter -> OA -> Virtuoso conversion problem

Hi baumanets

Such problems should not exist if your Encounter design uses OA inputs. If you are trying to convert a LEF-based design to OA format, perhaps you can refer to COS article 11736956 to see if it helps?

Hi baumanets

By the way, this question should be posted in the "Custom IC" forum and not this SKILL forum.

Quek,

I moved this to the correct forum. Thanks for pointing it out (and answering a whole bunch of questions!)

Hi Andrew

Thanks. : )

 Yes, I am trying to convert a LEF-based design to OA format.

Comand

lefin -lib gpdk090 -lef LEF/gsclib090_tech.lef  -overwrite -log LOG_DIR/tech.lefin

creates new tech library.

I read

Solution ID:11736956

and

Solution ID:20217208

But I want to attach design to the existing pdk library (not new tech library, created by lefin)

The comand 

lefin -lib gsclib090 -lef LEF/gsclib090_macro.lef -overwrite -log LOG_DIR/macro.lefin -view abstract -techRefs gpdk090

creates new std library with abstract view.

But I want to attach cells to my existing std, io, etc libraries.

Hi,

You need first to create the library that you would like to import the LEF into.

Please make sure at the library creation if you want to attach (only one library containing all the technology information) or to reference (if you want to use the incremental techfile capability).

After you run the lefin command with target library the newly created one. 

Can you please clarify what you mean by:" But I want to attach cells to my existing std, io, etc libraries." ?

I assume that you want your design to reference the newly created library.

In that case you need to run a remaster instances into the view.

The best would be to save from EDI :

Converting the EDI System Database to OpenAccess Database

Run the following commands to convert the EDI System database to OpenAccess database:

1. Run restoreDesign fe.enc.dat cellname
2. Run set init_lef_file ""
3. Run set init_oa_ref_lib " techLib"
   Other OpenAccess design reference libraries can also be appended. The first one should be the technology library.
4. Run  set init_oa_abstract_view   "abstract"
5. Run  set init_oa_layout_view   "layout"
6. Run  saveDesign   -cellview   {designLib topCellName viewName}

 Thanks,
