    cdb2oa warnings Reply
    Hello,

    I want to convert a design from IC5.1 to IC6.1.5.72 with cdb2oa, and I encounter this warnings:

    Warning (Technology Conversion) : rtuosoIccInfo : Layer AP has preferred routing direction 'horizontal'. Cannot set to 'orthogonal'.

    Warning (Technology Conversion) : rtuosoIccInfo : Layer M6 has preferred routing direction 'vertical'. Cannot set to 'orthogonal'.

    Warning (Technology Conversion) : rtuosoIccInfo : Layer M5 has preferred routing direction 'horizontal'. Cannot set to 'orthogonal'.

    Warning (Technology Conversion) : rtuosoIccInfo : Layer M4 has preferred routing direction 'vertical'. Cannot set to 'orthogonal'.

    Warning (Technology Conversion) : rtuosoIccInfo : Layer M3 has preferred routing direction 'horizontal'. Cannot set to 'orthogonal'.

    Warning (Technology Conversion) : rtuosoIccInfo : Layer M2 has preferred routing direction 'vertical'. Cannot set to 'orthogonal'.

    Warning (Technology Conversion) : rtuosoIccInfo : Layer M1 has preferred routing direction 'horizontal'. Cannot set to 'orthogonal'.

    Warning (Technology Conversion) : rtuosoIccInfo : 'none' is not a valid icc function. Ignoring layer 'PO'.

    I don't see why it want to change 'horizontal'/'vertical' to 'orthogonal'. I find anything about it in the documentation and in the internet.

    Regards,

    Benoit.

    Hi Benoit,

    You can ignore this warning.

    Actually the layer direction is already set in the technology but you have some rules concerning the layer routing for ICC (VCAR or CCAR) which specify it as orthogonal and the tool mention that it could not modify it as orthogonal does not exist in OA.

     Regards,
    Alex
