    mapping number of segments of rppo resistance from one technology to another Reply

    Hi,

    I am trying to convert schematics of one technology to another ,

    i could able to convert all transistors, but i am unable to do for rppo number of segmets .

     can some one please help.

    thanks.

    You really will need to give more details as to exactly what it is you have tried, and what you are unable to do. From the level of information you've provided so far, I doubt anyone would be able to help you (I certainly can't; I have no idea what your issue is)

    Kind Regards,

    Andrew

    Hi Andrew,

     I have a skill script using which i am porting schematics of one technology to another.

    That script maps old-cell (nmos) parameters (like l,w,mult)  to new-cell (nch) parameters (len,wid,m).

    I have to enter old-parameters (like l,w,mult) and new-parameters (like len,wid,m) to work with the script.

    for transistors that script converts properly (like nmos ,nmos2v5 to nch ,nch_25) .

    but for resistors it is converting length ,width and multiplier correctly but the number of segments are not been taken into new-cell (i used segments as parameter) .

    example:

    len-->L (works)

    wid-->W (works)

    segments-->segments (does not work)

    --thanks

    My guess is that you've either got the parameter name wrong, or you need to call the CDF callbacks (see solution 11018344)
