How can I write out .lib file of a digital module designed in virtuoso ?
Also If I want to import this module as a digital block to encounter, how can I make it as a macro/cell ? How to take care of this while
writing out lef from virtuoso ?
LEF can be written with File->Export->LEF. .lib could be generated with the Liberate family of tools - there's not really a direct way of writing .LIB from Virtuoso because it generally needs characterization. There is the Tools->Characterization and Modelling->Black Box Liberty (MS) menu - not sureif that's really what you want either.
In reply to Andrew Beckett:
Thanks for the help..
The issue with lef is that once I export lef from virtuoso and read this to encounter,its not recognised by encounter as a macro.
Can we use the lef generated by File->Export->LEF in virtuoso directly to encounter ? Or anything else need to be done for generating abstract views so as to deal with the module as a macro in encounter?
In reply to Shameel:
If you have already generated your abstract then you could use (Shift+Q) Edit Master Properties and set the 'cellType' to 'block'.
Otherwise you can do the setting using abstract generator when creating teh abstract by moving the cell to the 'macro' 'bin'.
Another solution in case you have to do it for multiple cellviews is to use teh CIW -> Tools -> Set cellType.
In reply to Alex Soyer:
I have made the option " CIW -> Tools -> Set cellType> * " Still encounter does n't recognize it as MACRO
If I change CLASS to PAD instead of CORE or BLOCK ,encounter
is recognizing it as IO pad with pins and exactly how I need it; except
that it is IO .
But its not supporting CORE,BLOCKIs there any attribute in lef that does n't support for CORE but IO ?
For CORE you need additional information like the sitePattern (which is the legal row site pattern in which you can place it) and SYMMETRY set to XY (allowed orientation)
For BLOCK I think the missing information is the SYMMETRY which is mots of the time ANY.
In order to set the information you need to open the cellview and do Shift+Q and then complete the Edit Cellview Properties form as mentioned above.
