-==== Running Book Examples ====
-Basic instructions for simulating CMOS book examples using Cadence Spectre (refer to the Cadence [[http://cmosedu.com/videos/cadence/cadence_videos.htm|Tutorials]] for details):
-  *   With Cadence running use the Library Manager to open the schematic view of a cell for simulation using Virtuoso Schematic Editor (SE)
-  *   In the menu of the SE Window select Launch -> ADE L to open the Virtuoso Analog Design Environment (ADE) Window. Use the ‘Always’ option when prompted for license.
-  *   In the ADE Window’s menu select Setup -> Simulator/Directory/Host… and then set the Simulator menu item
-    * For most simulations Spectre will be used, if UltraSim or some other simulator is used it will be noted on the schematic. In your environment, Spectre should already be set up as the default simulator.
-  * Next, again in the ADE Window’s menu, select Session -> Load State
-    * set the Load State Option to **Cellview** and press OK
-  * Finally, in the ADE Window’s menu select Simulation -> Netlist and Run (or just hit the green button) to simulate.

   * Use the MOSIS Scalable CMOS (SCMOS) **SUBM** **design rules** for your ece510 layouts. The design rules can be found in this [[http://mosis.com/files/scmos/scmos.pdf|document]]. Note that the design rules are given in terms of lambda (=0.3u) while Cadence Virtuoso uses absolute values without any scaling. Thus in your layouts, multiply all design rule numbers by 0.3u for final layout dimensions. Eg. the minimum N-well width of 12 translates into 12*0.3u=3.6u in Virtuoso layout.
