CHAPTER 1Overview1
OverviewLast modified 10/26/00About this ManualThis manual describes the features of the AM-AHB Support Package including: Features of the support packagePackage installationConfigurationGuidelines for connecting to the system under testThe headers on any page will show you when the last changes were made to the manual. Comparethis the date in headers of the pdf version on the website to ensure you have the most up-to-date information.Support DescriptionThe AM-AHB Support Package provides timing analysis, state analysis and both ARM and Thumbdisassembly support for ARM microprocessor cores. This package is designed to capture and analyzethe AMBA-AHB bus activity of an ARM processor.Since the ARM is a microprocessor core, it is not possible to provide a support package that will workcorrectly with all possible ARM configurations, due to specific ASIC implementation differenceswhich might arise. However, this support is compatible with the AMBA-AHB specification, and isdesigned to operate directly on the ARM Integrator development boards, as well as other boards thatprovide access to the required address, data and bus control signals (see “Connecting to the AMBAAHB Bus” on page 9).The AM-AHB Logic Analyzer runs on mainframes equipped with logic analyzer modules that are102 channels or wider. At the time this manual was printed, the supported logic analysis modulesinclude the TLA7L3, TLA7M3, and TLA7N3 102 channel modules, and the TLA7L4, TLA7M4,TLA7N4 and TLA7P4 136 channel modules.Support FeaturesThis package is designed to operate on the AMBA-AHB bus. In addition to the timing and state analysis support, this package provides disassembly support for both ARM and Thumb instructions, inboth little and big endian modes. ARM/Thumb detection is automatic.2AM-AHB TLA Logic Analyzer

If your ARM board uses the same pinout specification, the AMAHB Logic Analyzer will function correctly.If you are building a new board and want to use the AM-AHB Logic Analyzer, design the pinoutsaccording to the Mictor pinout specification. For details of the specification, see the ARM Integrator/AM User Guide, available at www.arm.com.If your module does not adhere to the Mictor pinout specification NEX-HDSWIZ adapters are available from New Wave PDG. See www.busboards.com for adaptor specifications and ordering information.AM-AHB TLA Logic Analyzer9
Configuring the AM-AHB Support PackageLast modified 10/26/00The Mictor connector is described in Tektronix document 070-9793-02, available from Tektronix, athttp://www.tek.com.Clocking Options for AM-AHB SupportThe AM-AHB Microprocessor Support Package provides several customized clocking options thatare tailored to the characteristics of the AMBA-AHB bus. Clicking on the More. button shown in theSetup menu in Figure 4 will take you to the Custom Clocking Options dialog box, shown below inFigure 5.FIGURE 5. Custom Clock Options dialog box.The following clocking options are available:Valid AHB CyclesThis is the most commonly used of the clocking options, and is recommended for conforming AMBA-AHB bus implementations. With thisclocking option, HREADY is utilized to suppress bus wait state cycles, andHTRAN[1] is utilized to suppress address-only bus cycles.Rising Edge of HCLKThis clocking option samples the address, control, and data groups on therising edge of HCLK. This clocking option is useful for debugging purposes, and can be used along with the Waveform displays of the TLA tostudy low-level AMBA-AHB bus activity.The following signals are required for each clocking option:Custom Clocking OptionRising Edge of HCLKValid AHB CyclesHCLKHREADYHTRAN[1]ÿÿÿÿThese clocking options should allow the support package to acquire relevant AMBA-AHB bus activity in the majority of cases, but will not necessarily be appropriate for all implementations, due toimplementation-specific differences in bus architecture, signal timing, etc. If a customized clockingmethod is required for a specific implementation, contact Dragonfly Software Development for information about adding additional support to the package.
