    IBIS to DML problem Reply

    Hi
    I had created a ibis model, it pass ibischk 4.1 without error & warning.
    When I convert ibis to dml it gives the following warning
    WARNING @line 300: MYMODEL_LVTTL_F_2 PullUp: Overall typical area exceeds overall maximum area

    WARNING @line 300: MYMODEL_LVTTL_F_2 PullUp: Overall minimum area exceeds overall typical area

    WARNING @line 215: MYMODEL_LVTTL_F_2 PullDown: Overall typical area exceeds overall maximum area

    WARNING @line 215: MYMODEL_LVTTL_F_2 PullDown: Overall minimum area exceeds overall typical area

    WARNING @line 169: MYMODEL_LVTTL_F_2 PowerClamp: Overall minimum area exceeds overall typical area


    WARNING @line 76: MYMODEL_LVTTL_F_2 GroundClamp: Overall minimum area exceeds overall typical area


    WARNING @line 76: MYMODEL_LVTTL_F_2 GroundClamp: Slope at end is not flat - point added


    Here is sample mymodel.ibs attacked.
    I am using SPB 15.2

    ibis2signoise added some more checks that ibischk.
    there are two kinds of warnings:
    1. maximum/minimum exceeded typical values in the curves. These are not normal for the different corners. It is cautionable but may not be an error;
    2. last warning message is to flat the end point. This is necessary for the curve data for the extrapolate of the curves for the simulations since IBIS asked for the stabalization of the buffer status in the end.

    Hope this helps.
    Lance
