substrate noise analysis

whlinfei

Hi All,

 I am designing a switching amplifier using a CMOS 65nm process with a normal QFN package. So the noise induced by the switching output stage is quite large. The power supplies are separated for analog and power parts. But the noise can still get through by substrate.

 I want to find out what is the noise level at the analog domain.

Can anyone help me out how I can run this analysis?

Suppose I have the general floorplan and the model of the noise source.

  • Hi Quek,

     

    Thank you.

     No. The Substrate Extraction option is available in the setup tab. I check with the licence manager on our side and confirmed we do have XL licence.

    The output format is extracted view.

    Do you mean that if the Substrate Extraction and the output format are correctly choosen, the substrate extraction tab will pop out automatically?

    In my case, it didn't. Is there anyway to get the tab manually?

     Thank you.

     Best Regards,
