The BE-64 is a C size VXI card which houses the digital resource required in digital test and troubleshooting applications.

BE-64 FEATURES

SINGLE C SIZE MESSAGE BASED VXI MODULE.

SCPI COMMAND SET

64 I/O CHANNELS X 32 K BITS / CHANNEL

	32K I/O memory subdivided into multiple data tables
	Data rates from DC to 25 Mhz

16 TIMING SETS

Each timing set is defined by a 256 bit x 24 bit memory

Timing sets are docked by a 50, 20 or 10 Mhz (20, 50 or 100 ns resolution) or external dock (50 MHz max.)

Each timing set includes the following:

	8 user defined output signals - TSOUT1 thru TSOUT8
	3 test inputs (handshake) signals (2 level and 1 edge sensitive input)
	Field 1 and Field 2 control signals
	Programmable cell delay (from 1 to 64K clocks)
	Programmable timeout (from 1 to 32K clocks)
	3 Programmable sync signals

SEQUENCE DEFINITION

	Programmable idle sequence
	Program from 1 to 16 sequences where each sequence . . .
	Selects one of the sixteen timing sets
	Selects a data table
	Selects a loop count from 1 to 64K (or continuous)
	Zero time delay between timing sets, data tables and sequences
	Single cycle (all sequences) or continuous

24 PROGRAMMABLE SET / SENSE SIGNALS

MACRO COMMANDS

	UUT RAM and ROM Test
	Learn CRC's from input data tables & serial data channels
	Compare response tables to expect tables
	Algorithmic fill and copy (data tables and timing sets)

WORD GENERATOR

The word generator mode of the Model BE-64 incorporates the following features.64 I/O channels x 32K bits/channel, 25 Mhz data rates, Tri state output control 32 I/O channels x 64K bits/channel, 50 Mhz data rates. The 32K memories are software allocated into tables. Up to 32K tables may be defined. Table length is programmed from 1 word to 32K words. Each table may be looped from 1 to 64K times, or run in continuous mode. Up to 16 tables can be hardware linked together, generating zero dead time between tables. Continuous operation of an "Idle" table which can run while downloading new data. Each table can be input or output.

LOGIC RECORDER

The BE-64 can be programmed to record up to 64 channels by 32K/channel.

STIMULUS/RESPONSE TESTING

For test applications where test vectors are available, the Model BE-64 can be programmed to transmit or receive 64 channels by 32K bits per channel at frequencies to 25 Mhz.

BUS STRUCTURED INTERFACE SIMULATION

Bus structured interfaces are simulated exactly like the bus structured interface of a microprocessor. The architecture of the BE-64 has enabled Talon customers to simulate well over 1000 different digital interfaces. These interfaces range from a serial T2 communication interface to a high speed VME bus structured interface. Talon offers "set up" configurations for the following bus structured interfaces.

VME bus, VXI bus, Multibus, AT bus, NuBus, SCSI bus, Microchannel, EISA bus, S bus

NON BUS STRUCTURED INTERFACE SIMULATION

The Model BE-64 word generator model allows the simulation of almost any user defined digital interface.

MICROPROCESSOR BUS EMULATION

The Model BE-64 can be programmed to simulate the bus structured interface of any microprocessor incorporating an address and data bus, each bus not exceeding 32 bits in width. All timing and control signals are simulated, generating bus cycles to 50 Mhz.
