Make my own schematic ?

geo24

Hi Guys,

For my ADC project, I wanna use my own design MOM (Metal-oxide-metal) capacitor. I have draw the layout of MOM cap and it's DRC clean. 

So how can I make a new schematic and corresponding to the new MOM layout ? I want to pass the LVS.

Thank you,

Geo

    Hi Geo

    You can do it as follows:

    a. Create an empty schematic
    b. Add the appropriate pins. E.g. if the momcap layout contains PLUS, MINUS pins, please also add PLUS and MINUS pins in the schematic
    c. Go to "Create->Cellview->From Cellview" to generate a symbol
    d. The symbol is now ready for use in another schematic for LVS


    Best regards

    In addition to what Quek says, the biggest issue will be whether your LVS deck recognises the new structure as that device. You might have to add rules to the LVS deck to identify the structure, the pins, and connectivity (and parameters).

    Regards,

    Andrew.

    Thank you Quek. I was thinking use a ideal cap from analogLib, but somehow can not make LVS pass.

    Hi Yuan

    Would you please let us know why LVS did not pass? I think there must be some error/warning in the LVS report file, log file, etc.


    Best regards
