    metal density at chip level.

    minimum metal density layer Hi, No that is false, having density above maximum is not good at all, it is even worse than having it less than min. You really need to stick at the min/max bounds. If you have too much metal, than the dielectric between metal tracks is most likely to get missed...

    Why the maximum limit for the diffusion density will be present?

    Re: Diffusion Density Omsi, Too much diffusion is most likely to prevent the lithography/etching of the trench isolation patterns, especially in the nano technologies. A high density of diffusion would lead in a low density of the isolation dielectric. density is very important for the...

    Spectre error: Illegal library definition found in netlist

    Re: Error using spectre Hi, This error occurs most likely because your spectre model file contains many sections. You need to tell to spectre which section it has to include. I guess your netlist contains : include "<YOUR_MODEL_PATH>/spectreModelFile.scs" but it should be like include...
