Hello everyone,
I am currently working on a project involving TSMC 0.18um deep
submicron technology in cadence. My problem is as below . I have the technology library file of TSMC 0.18µm deep submicron technology in my cadence . All though
the tecnology supports deep nwell layer , i am not able to find the layer in LSW window or in the add layers option of the LSW window. I donot see any deep nwell layer files defined at all. I am not able to proceed further without this layer.
Is there any way i can get that layer in cadence ?
Is it possible to define the layers and if so how to do it so that i get no DRC errors?
Hi meitolake,
No i cannot find deep nwell layer defined anywhere. I even tried using magic , but even there in the library file used, there is no definition of deep n well.
From what i know this is an optional layer. I donot know how to define that layer and use it in my layout.
Hi layoutmaster,
In 0.18 also Deep Nwell is an optional mask. Any idea how to use it in layout ..
I think, 'optional ' means that this layer can be drawn as you like, not mean that can be defined as you like.
I do not recommend modifying the technology file.
Can you get any help from the documentation of this process?
