Layout and LVS of a non-standard device!

Ueue

Hi,

I'm currently trying to draw the layout of a device not present in the library of my technology. So, I think to create a symbol to put in the schematic of my circuit and after to draw the complete layout.

When I will finish the layout, what can I do to execute the LVS?

I think the LVS will not recognize the new device. Someone suggested me to add a lot of labels in my circuit near to the non-standard devices.

Is it a good idea?

Are there other more efficient method to execute the LVS of circuit with non-standard devices?

  • Sorry, you are right!

    I used for my simulation a model of a diode, obtained through TCAD simulations. So, the device doesn't exist in the technology library, but it has been used to design a rectifier!

    Now, I have to draw the layout of the circuit, but I think that if I simply draw the layout of the diode and associate a symbol view, the LVS will not work? A solution that someone suggested to me was to insert a lot of labels in the schematic and in the layout, in order to check that the connectivity is correct! Of corse, the LVS will have the errors due to the unknown devices, but at least the connectivity could be checked.

    I hope I was more clear...

    best regards,

    Stefano.
