But it can be as guidance to move the transistor or vias or reroute the wires to minimize the used of the wire. It can be draw with color pencil or dry-erase markers.  \nStick Diagram  \n􀁹 Layout construct from shapes like rectangular or squares meanwhile stick diagrams represents relative positions of transistors with rectangular or mark (X) as component symbols and lines as wires.  \n􀁹 The wires symbol can be in various colors such as red for poly, green for n-diffusion, yellow for p-diffusion and blue for metal1 as shown in Figure (next slide).  \n􀁹 Otherwise, the wire also can be drawing in different types of lines such as straight line, dotted line, short dashed line and etc.  \n| ___________\u003Cbr>_ _ _ _ _ _ _ _\u003Cbr>_ _ _ _ _ _ _ _\u003Cbr>_ _ _ _ _ _ _ _\u003Cbr>_ _ _ _ _ _ _ _\u003Cbr>_ _ _ _ _ _ _ _ | Poly\u003Cbr>ndiff\u003Cbr>pdiff\u003Cbr>metal 1\u003Cbr>metal 2\u003Cbr>metal 3 |\n| --- | --- |\n\nThe wires symbol  \nStick Diagram  \n􀁹 There are a few simple rules for constructing stick diagram to ensure the stick diagram is corresponding toa feasible layout.  \n􀁹 First, the wires must be drawn in horizontal or vertical lines and two wires.  \n􀁹 Second, two wires segments on the same layer which cross are electrically connected so vias is used to connected wires that do not interact.  \n􀁹 Table (next slide) shows the complete rules of possible interactions between layers which show that how wireson different layers allowed to cross each other.  \n􀁹 This table is derived from the manufacturing design rule  \nRules for possible interactions between layers (connection rules)  \n\n| metal3 | metal2 | metal1 | Poly | ndiff | pdiff |  |\n| --- | --- | --- | --- | --- | --- | --- |\n| short | open | open | open | open | open | metal3 |\n|  | short | open | open | open | open | metal2 |\n|  |  | short | open | open | open | metal1 |\n|  |  |  | short | n-type | p-type | Poly |\n|  |  |  |  | short | illegal | ndiff |\n|  |  |  |  |  | short | pdiff |\n\nStick Diagram Steps  \n1) Construct a logic graph of the schematic.  \n􀁹 Figure 8.1 shows the schematic and graph for equation . From this figure, identify each transistor by a unique name of its gate signal (A, B, C, D, and E).Then identify each connection to the transistor by a unique name (1, 2, 3 and 4) .  \n􀁹 Figure 8.1- (next slide)  \nFig 8.1: Schematic & graph  \nStick Diagram Steps  \n2) Construct one Euler path for both the Pull up and Pull down network  \n􀁹 Figure 8.2 shows the example of Euler Path. Euler paths are defined by a path the traverses each node in the path, such that each edge is visited only once.The pathis defined by the order of each transistor name. If the path traverses transistor A then B then C.Then the path name is {A, B, C}.The Euler path of the Pull up network must be the same as the path of the Pull down network. Euler paths are not necessarily unique. It may be necessary to redefine the function to find a Euler path.","cbCaitlYOsK4C9yj","https://ap.wps.com/l/cbCaitlYOsK4C9yj","pdf",693416,25,"English","# Stick Diagram\n## Differences: Stick Diagram vs Layout\n## Representation: Shapes, Wires, and Colors\n## Rules for Constructing Stick Diagrams\n## Rules for Possible Interactions Between Layers\n## Stick Diagram Steps\n## Step 1: Logic Graph and Naming\n## Step 2: Euler Paths for Pull-Up and Pull-Down","[{\"question\":\"What is a stick diagram in IC layout design?\",\"answer\":\"A stick diagram is a graphical view of a layout, representing the relative positions of transistors and the wiring.
