spram
Hello friends,
I have another question for you:
In my design there are few kinds of spram (single port ram).
My question is about the pin out of these rams, they have the same pins in every metal layer from M1 to M4 (the upper layer in the specific rams). I mean that there is a duplication of the ram pins…
Why the duplication of the pins is for ? (For more convenient routing choice for the router? , and how the router know what to choose? , can the user determine which pins on which layer will be connected –"routed"? )
I understand that when running the memory compiler, the designer choose what is the mask layer ….. – How this is connected to my question?
Many Thx again,
faeez
