Bluetooth DesignGuide QuickStart

The Bluetooth DesignGuide QuickStart provides an introduction to the content and use of the Bluetooth DesignGuide.
To learn more, refer to Bluetooth DesignGuide Reference.

The Bluetooth DesignGuide application package for the Agilent Advanced Design System (ADS), contains various system test benches and reference designs (e.g., an optimal low-IF receiver) for the RF portion of the Bluetooth physical layer. It allows for the investigation of system performance from simple EYE diagrams, to BER (bit error rate) when impairments such as AWGN, VCO phase noise, multipath, and/or co-channel, adjacent-channel, intermodulation and pulsed-RF interference are present. In many cases, the receivers EYE diagram can be observed in real time during simulation while adjusting the level of the signal or interferer via an interactive slider.

The DesignGuide also addresses some phase-lock-loop (PLL) and voltage-controlled oscillation (VCO) design issues and can help you select the best demodulator for your receiver.

Using DesignGuides

All DesignGuides can be accessed in the Schematic window using either the cascading menus or dialog boxes. Your preferred method can be configure in the Advanced Design System Main window. Select the DesignGuide menu.

Note
This document describes access through the cascading menu preference. If you are running the program through the selection dialog box method, the appearance and interface will be slightly different.

The commands in this menu are as follows:

DesignGuide Studio Documentation > Developer Studio Documentation This is only available if you installed the DesignGuide Developer Studio. Selecting this brings up the DesignGuide Developer Studio documentation. You can also access this documentation by selecting Help > Topics and Index > DesignGuides > DesignGuide Developer Studio from any ADS program window.
DesignGuide Developer Studio > Start DesignGuide Studio This is only available if you installed the DesignGuide Developer Studio. Selecting it launches the initial Developer Studio dialog box.
Add DesignGuide brings up a directory browser in which you can add a DesignGuide to your installation. This is primarily used with DesignGuides that are custom-built using Developer Studio.
List/Remove DesignGuide brings up a list of your installed DesignGuides. To remove a Design Guide, select any you wish to uninstall and choose the Remove button.
Preferences brings up a dialog box that allows you to:

Disable the DesignGuide menu commands (except Preferences) in the Main window. By unchecking this box, the complete DesignGuide menu and all of it's commands will be removed in the Schematic and Layout windows.
Select the interface method you prefer (cascading menus or dialog boxes).

You must close and restart the program for preference changes to take effect.

Note
On PC systems, Windows resource issues can limit the use of cascading menus, opening multiple windows could destabilize your system. In these situations using the dialog box menu is recommended.

Accessing Documentation

To access the documentation for the DesignGuide, select either of the following:

DesignGuide > Bluetooth > Bluetooth DesignGuide Documentation (from ADS Schematic window)
Help > Topics and Index > DesignGuides > Bluetooth (from any ADS program window)

The Bluetooth DesignGuide Menu

The Bluetooth DesignGuide menu, located in the Schematic or Layout window under DesignGuide, provides convenient access to test benches, subnetworks and data displays. It may be installed as a standalone, or along with other DesignGuides.

The contents of the Bluetooth DesignGuide menu are divided into several categories:

Basic System Test Benches. These test benches provide tutorial simulations using the Bluetooth RF segment and allow you to evaluate filtering options for the transmitter.
Component/Subnetwork Evaluations . These simulations are designed to help you understand and validate many of the built-in subnetworks used in the system test benches.
VCO/Phase-Locked-Loop (PLL) Investigations. These are simulations of phase-lock-looped topologies address timing and noise issues.
Multipath Propagation Test Benches. These simulations include multipath models for investigating system performance under non-ideal indoor propagation conditions.
System Compliance Tests. These system test benches are designed to evaluate sensitivity and blocking performance.
Medium Rate Radio 1.0 Improvements. These simulations include two modulation formats for proposed enhancements to Bluetooth radios that allow them to operate at higher data rates.
WLAN (802.11) Interference. An 802.11 signal source is combined with a Bluetooth radio to allow investigations of WLAN interference effects on Bluetooth performance.

For each category, moving the cursor to the right will open a menu displaying the available items. Each selection (except those beginning with Display) will open a top-level test bench schematic and in many cases, a data display. The selections beginning with Display open additional data displays, after the test bench listed above it has opened. You can also access help, BlueTooth DesignGuide documentation and an About... box from this menu.

Displaying Simulation Data

Some test benches have real-time Tk displays that open each time a simulation is performed. Other test benches automatically open one or more Data Display windows when selected. In several instances, for example a test bench that is capable of BER calculations, additional data displays are available. When a Data Display having the same name as the design has been closed, it can be re-accessed by selecting the Display Simulation Results option listed on the menu, once the test bench has opened.

Interactive Simulations

Some simulations using Tk displays have interactive sliders that allow a parameter to be adjusted during the simulation. To run a non-interactive simulation where output data is only collected by sinks, (i.e., time-domain or spectrum measurements), all Tk items must be de-activated. The TkPowerControl, TkPowerControl2 or TkPowerControl_ForRFOffset subnetwork must also be de-activated and bypassed with a wire because it contains an interactive slider.
