Library Path display issue

wenckey

I met a problem when I define the library in cds.lib file.

If I define like below:

DEFINE    LIBA    PATHA

SOFTDEFINE    LIBA   PATHB

WHen the  PATHA and  PATHB all exist, in Library Path, it will show the PATHB without any problem.

If the  PATHA is exist and the PATHB is not exist, the Library Path will show the PATHB in red, but it will point the LIBA to the  PATHA. Then if I show the property of LIBA, it will show the PATHA.

My question is how can I make the library path to show the correct path if the SOFTDEFINE path is not exist.

Thanks

  • Kevin,

    This is a very odd setup. Why would you define the path to be two different locations? It makes no sense.

    The library path editor always shows in red any paths that don't exist. The path editor is a tool to help you construct the cds.lib - I wouldn't have thought it mattered that much what colour they are shown in.

    More importantly, Virtuoso (and other tools) will complain if both paths exist:

    *WARNING* LIB LIBA from File /export/home/myuser/support/forum/cds.lib Line 10 redefines
    LIB LIBA from the same file (defined earlier.)

    Normally you'd use UNDEFINE to undefine an earlier definition. Either way, it's really unclear what your objective is here.

    Thanks for your reply.

    I will figure out why we set like this.

    Can you tell me what's the difference between DEFINE and SOFTDEFINE?

    Thanks

    Hi, Andrew:

    Is there a way to set two path for a lib (since we don't know which path is valid or maybe the two paths are all valid), and cadence would choose the valid one (if all valid, choose the first setting or last setting)?

    You could use SOFTDEFINE for both. If both exist, it will give a warning and pick the last one defined. If only one exists, it will silently pick just that one. If neither exist, it will silently not show that library in the available libraries.

    Andrew.
