I am a newbie in Layout. Hope anyone can help me to answer the question below:
1. Why should we separate 2 metal lines far apart? Except to avoid shortening and crosstalk.
2. If a DRC for spacing of 2 metal is "x", why sometime we need to make it for greater than x?
3. What are the important of maintaining the symetry of layout?
4. What is matching in layout? is it about Symmetry and common centroid between devices ?
5. What are the things that we need to consider when drawing a analog/digital layout?
6. what is "finger" in layout?
7. How to minimise the area of layout? except share the diffusion of transistor?
8. What is the most concern issue of a layout engineer?
9. What are the effect of crosstalk? induce noise?
10. How is one evaluate a layout? What aspect we should look into? parasitic resistance/capacitance/inductance? what more?
Please kindly add in any information that a newbie should know.
thanks a lot.
cheers!
