How to create layout xl for user defined pcell with same parameters as in schematic??

KarthikJaiho

 

Hi ,

       I need to create a layout using layout xl. The thing is i need to get the parameters as in schematic for pcells in layout.

Example:-

      nmos has a schematic and layout.  Now i created a pcell with this nmos like nmos_esd with two parameters length and width. And copied nmos schematic and renamed to nmos_esd. 

      But when i tried using "generate all from source" option in layout xl. I am getting corresponding nmos_esd. But the parameters are default and i cant able to edit. Is there any way to map user defined pcell parameters?? Please help..

Thanks & Regards,

 Karthik .

  • Karthik,

    You shouldn't need to "map parameters" - it should use the same parameters on the schematic as on the layout. My only guess is that your nmos_esd pcell is using different parameters than the CDF parameters used on the original nmos symbol instances.

    The best thing to do would be to contact customer support so that you can share the data - it's very hard to know what you're doing wrong based on the very limited information you've given.

    Regards,

    Andrew.
