Page 5: General Description
1 GENERAL DESCRIPTION VM-DBA is a new test and diagnostic module for VME / VME64x bus systems which visualizes activities on all VME bus lines on the set of front-panel LED’s, but also allows one to digitize individual waveforms of all these bus lines into 2kBit long storage memories, for a subsequent readout via VME or USB interfaces.
Page 6: Interface / Firmware Information
VME master (typically in system slot 1 on the left) and the first slave module right of it.. Thus a suggested slot position would be slot 2. The VM-DBA should not be located left of a VME master or to the right of any other slave module.
Page 7: Vme Base Address
VME Base Address The VM-DBA base addresses for all modes (A16/A24/A32) are set via jumpers in the JP 4 array on the PCB. A jumper that is inserted in the left position (below “1”) counts as a 1 in the base address bit pattern.
Page 8: Vm-Dba Led Display
In the direct or “raw” mode, the LED’s indicate the actual state of the lines, while in latched mode, the states of the lines are captured either by the DTACK*, or by BERR*, or by BBSY*, or by a pseudo-DTACK* signal generated by VM-DBA itself. In the WIENER, Plein & Baus GmbH...
Page 9 The state of power lines +5V, +3.3V, +12V, and -12V and the SYSCLK line are displayed “as-is”. In addition to displaying the state of the VME bus lines, VM-DBA displays on selected LED’s its operating mode or state, as well as the occurrence of events of importance, as indicted in the table below.

VME master. Please refer to the VM-USB manual for programming and use of this controller. In case of VM-DBA operation through it’s USB port only the “VM/DBA” tab for setting and reading data as well as the “Flash Operations” tab for firmware upgrades are used. All other tabs are disabled.
Page 14: Irq Setup
The LED display of VM-DBA freezes at the detection of BERR, requiring a reset to re- activate the display. IRQ-enabled mode VM-DBA generates an IRQ upon detecting a valid IRQ trigger. Subsequently VM-DBA handles the whole IRQ cycle. Passive mode The response of VM-DBA to VME commands is suppressed (with the exception of an unlocking sequence).
Page 15 In case of analyzing rare occurring VME bus failures / states it is possible to configure and start the VM-DBA bus analyzer for a certain condition and leave it without being connected via USB or running the XXDBAwin software. The red AQ LED indicates that the VM-DBA is in acquire mode.
Page 16: Vme Bus Analyzer - Example For Berr Condition
1) Set the waveform acquisition trigger condition to “BusError” 2) Define the pre-trigger range to be large enough (example 900 = 9µs) in order to show the VME cycles which caused the bus error. WIENER, Plein & Baus GmbH www.wiener-d.com...
Page 17 BERR at time = 0 (trigger, shown with dashed line) and the last VME cycles about 8µs before the timed out which caused the bus error. The displayed lines can be changed by checking or un-checking the related fields. WIENER, Plein & Baus GmbH www.wiener-d.com...
Page 18: Vme Bus Analyzer - Example For Address Condition
As an example the bus analyzer should be triggered when reading or writing to an address in the range 0x7000 to 0x7ffff, the AM value is ignored: 1) Set the waveform acquisition trigger condition to “A AND NOT AM” and the matching conditions for address (A) and address modifier (AM) WIENER, Plein & Baus GmbH www.wiener-d.com...

2) Change the IRQ logic condition in case needed, the default would trigger on any IRQ. (Please note that in this example the IRQ is generated by the VM-DBA on an incoming logic signal into the IN-Input. This is defined in the IRQ setup fields)

USB2 port of the VM-DBA using bulk-transfer mode. Borrowing from the USB language, the buffers to be written to the VM-DBA will be called Out Packets, and they are sent to pipe 0 of the USB port. The buffers to be read will be called In Packets, and they are read from pipe 2 of the USB port.
Page 24 The base address bits (the 5 most significant bits in the full VME address) are disregarded as it is presumed to apply to the VM-DBA itself.

Page 28: Guide To Using The Vme Bus Waveform Storage And Viewing Facility
Guide to using the VME bus waveform storage and viewing facility VM-DBA is capable of storing the states of 95 VME bus lines in 2048 consecutive time steps at a rate of either 100 MS (mega samples per second) or 200 MS. The sampling rate is user- programmable.

Page 31: Processing Of The Acquired Waveforms
When in continuous waveform acquisition mode and upon the detection of a valid trigger signal, VM-DBA completes storage of waveforms as specified in the setup. At this time the red AQ LED should turn off and the blue LED labeled F4 should begin blinking. If this is not the case, begin the cycle from the beginning.
Page 32: Special Modes Of Operation
SPECIAL MODES OF OPERATION For test purposes, VM-DBA may be set to operate in modes other than the default mode with the display reflecting the states of the VME bus lines latched or stretched at the last VME activity, and the unit responsive when addressed via VME or USB interface. The modes are largely similar to those offered by the predecessor module VDIS-2, except that they are here controlled by internal registers rather than by front-panel switches.

As far as the exit from the passive mode is concerned, unlocking is necessitated by the fact that while in passive mode, VM-DBA is not responsive to regular commands but still checks for the receipt of the “unlock” sequence. Then, upon detecting “unlock” it responds to the subsequent “exit from passive”...

Page 37: Irq Service Test
IRQ SERVICE TEST VM-DBA allows one to test the integrity of the IRQ handling net in the VME crate by issuing, upon detecting a valid trigger signal, an IRQ on any of the seven IRQ1 – IRQ7 lines. Subsequently it responds to the IAQ/IAQIN/AS inquiry by the IRQ handler by placing on VME bus data lines 0 –...
Page 38: Firmware Upgrade Procedure
10 FIRMWARE UPGRADE PROCEDURE The VM-DBA firmware can be updated through either the USB port or via VME by using the VM-USB controller. Please use the XXDBAWin program and get the latest firmware file from the www.wiener-d.com web site. 1. Check Base address of VM-DBA (following example shown for factory default Base address 0x78000000).
