 Hi All

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 ?

 

Thanks

  • Hi Shameel,

    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.

     Thanks,
    Alex
