The objective of this flow is to generate the layout of an analog circuit in an automated manner, in order to obtain early feedback on parasitics and device effects on circuit simulation. As a circuit designer you can thus identify issues early on and make necessary changes to quickly iterate through the flow which helps avoid costly changes late in the cycle and enables faster design convergence We demonstrate this flow using a sample and hold circuit based on a generic 45nm PDK Parasitic Aware Design Workshop ADE GXL's Parasitic Aware Design (PAD) features are used to investigate the effect of parasitic devices on a circuit.

This is especially important at lower process nodes where the design rules are complex and discovering errors early can save time and effort. Creating layout with Virtuoso IPVS turned on

IC 6.1.5 Virtuoso Schematic Editor XL PIEA, Conformal Low Power: Mixed- Signal Low Power Structural Verification Includes Rapid Adoption Kit with demo design (instructions are provided on how to setup user environment). Introduces the Power Intent Export Assistant (PIEA) feature that has been introduced in IC615 release. The power intent extracted is then verified by calling Conformal Low Power (CLP) which is built inside Virtuoso environment. Setup for PIEA Perform power intent extraction CPF Import Generate macro CPF and design CPF Perform low power verification by running CLP Schematic Model Generator Virtuoso Schematic Model Generator (SMG) is tightly integrated into the Virtuoso design environment and enables the generation of analog/mixed-signal behavioral models using a schematic-like representation of the behavioral model. The schematic view is then processed to generate the behavioral model. With this approach, behavioral modeling becomes easier to comprehend, communicate to involved team members and is better managed compared to manual textual entry. What is SMG Key benefits of SMG and a tutorial to demonstrate how to create a simple behavioral model for a voltage controlled oscillator (VCO) in the graphical modeling environment Schematic Model Generator (SMG) Creating Custom Connect Rules for AMS Simulation in ADE This document outlines the process used to create custom connect rules for running Mixed-Signal simulation in ADE with AMS Designer. The 5V connect rules that ship with the AMS simulator in the INCISIV installation will be copied to the working directory to create a set of custom connect rules for 1.5V. The example will show how to modify the rules file for 1.5V and how to build a connect rule library that will be recognized by the Connect Rule setup dialog in ADE. A short simulation will be used to validate the rules.

Spectre Device Checks Spectre device checking is used to monitor if devices in the circuit design are violating predefined set of conditions. The example describes the usage of the Spectre device checking feature. Set up device checks to insure that low voltage devices are not inadvertently used in a high voltage application. In the event a device is operating in an overvoltage condition, the check can show a warning or cause the simulation to stop on an error. Checking for conditions such as this can be an important productivity boost for long simulations since the simulation will stop right away when the condition is violated rather than finding out after the simulation has completed. Device Checking setup can be saved as with the ADE State for reuse or setup with an include file. Both methods will be explored. Using Spectre Save-Recover Spectre and APS have the capability to save a simulation state and restart the simulation from the saved state file. The simulation state for long simulations can be periodically saved to allow recovery from unforeseen circumstances, such as power outages or disk full issues. The save/recover methodology can also be used to restart simulations with different parameters or inputs. This example will illustrate using Spectre/APS Save-Recover from both ADE and command line based simulation. Using Spectre Save-Recover from ADE Using Spectre Save-Recover from the Command Line Additional Information/Quick Reference Basics of Inherited Connections Often times in design, the same cells need to be used in different parts of the circuit which use different power supply voltages. Inherited connections provide a mechanism to selectively override net connections by placing properties on the parent instance. Therefore the same cell can be used with different power supplies without the need for explicit power and ground pins. This document describes how inherited connections work with a sample design which shows how power and ground connections for the same cell can be different in the schematic hierarchy. Investigating Inherited Connections Setting Up Inherited Connections How Net Expressions Are Evaluated

Passing Parameters in the Schematic Hierarchy with ppar Schematics can be parameterized with ppar parameters to allow passing parameters from a parent instance to the lower level schematic (the child). This mechanism facilitates defining high level parameters to define the functionality of the circuit. The test case used for this example defines a strength parameter to set the drive capability of a buffer circuit. The strength parameter is passed down through the schematic hierarchy to define the size of the mos devices making up the buffer which in turn defines the current the buffer is capable of driving. Investigate Parameter Passing with ppar How to Setup Parameter Passing with ppar Adding ppar Parameters to Existing Schematics Setting defaults for ppar Parameters Power, Ground and Structured Routing Implementation Flow The flow leverages a combination of existing Virtuoso functionality, Virtuoso Routing TCL commands, and custom SKILL scripts to enable users to efficiently build custom power, ground and structured signal routes. An assisted flow where users have detailed control over how data is created but should rarely need to create or manipulate the data using the lowest level commands such as create, stretch, etc. Data is created and manipulated at high level, no need for time consuming zooming, placement or alignment of objects at the manufacturing grid level. The flow also supports creation of power and ground rough-in during early floorplanning. This flow is intended for Analog Mixed-Signal designs at the chip, block and device level in Virtuoso.
