How To Draw Layout In Cadence

How To Draw Layout In Cadence : CADENCE LAYOUT TUTORIAL Creating Layout of an inverter from a Schematic: Select the button corresponding to the Create New text as shown A Create New File window comes up. The Cell Name corresponds to the schematic name, leave it that way. The field corresponding to the View Name label should read Layout.. LAYOUT WITH LAMBDA RULES. Draw a rectangle that surrounds the pmos active area by 6 lambda (1.8 microns), you should get: We also need to add metal 1 above the contacts that needs to overlap the contacts by 1 lambda. It is now time to save your design (Design -> Save) and run a preliminary DRC. Go to Verify -> DRC . This parasitic probe ONLY works if you extracted the layout with the "parasitics" switch on. When All Else Fails Go googling for cadence tutorials - there are quite a few on the net. Try either "cadence tutorial" or "cadence hotkeys" and you'll find some good ones with nice pictures.. Example: Design and Simulation of an Inverter. Most of the commands in Cadence can be accessed in multiple ways: pull-down menus, shortcut keys, buttons in toolbars, etc. In the described example, all the commands are referenced by their position in the pull-down menus. The shortcut keys can be found from the pull-down menus as well.. Creating Full custom Layouts using Cadence' Virtuoso Layout Editor. First draw an n-well overlapping a little with the n-well of the Pfet and covering much of the VDD bus. Use the metal layer 'nw drw'. Now add a via connecting the RX (active) layer and the M1 layer on top of the Vdd bus, where M1 and NW overlap.. Before drawing on a new cell you should always setup the grid properties. • In the Virtuoso Layout Editing window, select Options => Display (or type ‘e’) to bring up the Display Options window shown below. Cadence Tutorial B: Layout, DRC, Extraction, and LVS 2. Layout It’s time to draw layout. Schematics are for verifying your design very roughly. They don’t consider physical features like parasitic capacitances. After determining your design variables by schematics, you need to draw layouts. Design flow of layouts is very similar to one of schematics, but it has additional step which is LVS check..
