2.4 Layout Design Examples The initial phase of layout design can be simplified significantly by the use of stick diagrams as shown in Fig.2.8. A stick diagram is a simplified layout form, which contains information related to each of the process steps, but does not contain the actual size of the individual features.

CMOS Mask layout & Stick Diagram Mask Notation 11-26 Steps in translating from layout to logic circuit 1. Try to simplify mask layout diagram by removal of extended metal and polysilicon lines 2. First draw coloured stick diagram for nMOS section and analyse All nMOS transistor nodes which connect to GND terminal are SOURCE nodes 3. Stick Diagram V DD A B A B A B A stick diagram is not a layout but gives the basic structure (including location,, orientation and interconnects) that will be instantiated in the actual layout itself Modifications can be made much more quickly on a stick diagram than on a layout Iteration may be needed to come up with a good layout structure Stick Diagrams STI CK DI AGRAMS Examples of Stick Diagrams Gnd V DD x x X X X X V DD x x Gnd 15 16 Stick Diagrams(NMOS): Basic Steps Normally, the first step is to draw two parallel metal (blue) VDD and GND rails. There should be enough space between them for other circuit elements. Next, Active (Green) paths must be drawn for required transistors.

Stick diagram examples pdf. Stick diagrams are useful for planning the layout and routing of integrated circuits. In a stick diagram, every line of a conducting material layer is represented by a line of a distinct color. In our study, we will use the basic color coding below: Polysilicon (gate) Active (n+ or p+ Metal1 n-Well boundary Other layers will be introduced later. Stick Diagrams: Euler Paths Peter Kogge University of Notre Dame Fall 2015, 2018 Based on material from Prof. Jay Brockman, Joseph Nahas, University of Notre Dame Prof. David Harris, Harvey Mudd College ...

Stick Diagrams - Some Rules Rule 4: In CMOS a demarcation line is drawn to avoid touching of p-diff with n-diff. All PMOS must lie on one side of the line and all NMOS will have to be on the other side. UNIT - II CIRCUIT DESIGN PROCESSES STICK DIAGRAMS. Examples of Stick Diagrams Stick Diagram and Representation 2/19/20174 A stick diagram is a stick representation for the layout and represented by simple lines. It shows all components with relative placement. It does not show exact placement, transistor sizes, wire lengths, wire widths, tub boundaries. n-diffusion (device well, local interconnect) Polysilicon (gate ...

Stick diagram layout of the complex CMOS gate. Order = A, E, B, D, C F =A⋅(D+E) +(B⋅C) Apply Euler path, find a common Euler path for both graphs .The Euler path is defined as an uninterrupted p ath that traverses each edge (branch) of the graph exactly once. In both cases, the Euler path starts at (x) and ends at (y). Order = E,D,A,B,C
