Does anybody know how to build my own PDK ?

alexyu

As a custom i am not very satisfy with foundry provide PDK, I want to do some customization, using different transistor geometry and different device model,  Does anybody know how to build my own PDK  based on foundry process ?  Until now I know, several component are required , parameterized cell builded using skill language, device model , does any body know what other requirement  do i need? and how to put them together ?

  • Hi Alex_yu,

    The symbols are often copied from those in analogLib; same for the stopping views. This may be automated using the SKILL function dbCopyCellView().

    The CDF is also often based on similar components in analogLib - but in practice the precise parameters will depend on both the device models and the parameters for your pcell. A good way to start is to use the cdfDump() function to dump the CDF from an existing component, and then you'll get the SKILL code needed to build the CDF - you can develop it from there to fit your needs.

    Regards,

    Andrew.
