"Create Wire" button (Shortcut = CTRL + Shift + w) Move the mouse cursor to the destination point and double-click to finish wiring.If you click the overlapping area of the multiple layers, choose the layer on "Choose Object to Tap" form.Click the wire or the electrode of the MOSFET to tap.Click "Create Wire" button on the toolbar.Click "Create Group" button on the toolbar to group the n-ch MOSFETs.Next, make abutting shape of two pairs of the series-connected transistors.Make abutting shape of the series-connected transistor first.If the transistors have both of a series connection and a parallel connection, create the abutting shape of the transistors through the following steps.The drain area or the source area of MOSFETs will be merged automatically and the abutting shape of two transistors will be created. Move the layout of the transistor close to the adjacent layout.You set the multiplier of p-ch MOSFET to two, therefore, the six transistors are generated for the four symbols. The multiplier of the transistor's property means the number of the parallel connections of the transistors. The layout patterns of the six transistors are shown in the layout editor, if you choose the four transistor's symbols on the schematic. Click "Generate Selected From Source" button of the toolbar on the bottom side of the layout editor.The 1-stage of the ring oscillator, which includes the four transistors, is adequate amount of the artwork. Choose the transistors on the schematic editor to create the layout of the transistors.ĭo not choose too many transistors, because too many parts of the transistors are shown in the layout editor and you may fall into confusion. The layout editor is accompanied by opening the schematic editor.If you set larger value, you can see the detailed layout, but the display speed is decreased. The display stop level controls the display depth of the hierarchy. Display Stop Level (Numerical input-box) on the toolbar = 10.Check the radio button on the form of the display options.If you want to increase the density of the layout, please refer the detailed design rule. The grid spacing shown in the following table is based on the common factor of all layers. The grid spacing is restricted by the design rules, which is determined in each layer. Menu of Layout editor: Options > Display.Initial configuration of Virtuoso layout editor.The layout view of rsoc is added in Library Manager and Virtuoso layout editor is launched.Cell = rosc, Type = layout、Open with = Layout XL.Menu of Library Manager: File > New > Cell View.The layout editor is included in the integrated development environment which you have already used for the schematic entry.
