Time Correlation available with Logic Analyzer

Internal Expansion Capability

For emulator modules which need more than 24 bits of address or more than 16 bits of data, the necessary extra bits are built into the emulator module itself.

External Trigger Inputs

• 2 inputs each with 8 channels
• 2 trigger qualifiers for each trigger level and channel group
• Each channel group can be assigned 2 trigger events for each level, definable using boolean formulae
• Static levels of the trigger inputs can be read at any time
• Free format definition of external trigger events
• Connection from digital test pods

Free Format Definition of Data Events

Data events can be specified with constants, masks, range or boolean formulae.

Trigger Unit

Programmed via a special Window

The programming of this complex trigger unit is done in an assembler-like language for maximum flexibility. Using this language, the programming of very complex trigger sequences or operations can be defined.

Fast programming via window

The most program settings can be made by menu based fast programming window

Symbolic Operation

All output operators and input variables can be input in symbolic form. The target program symbols can also be used.

Free Format Definition of Data, Address and Trigger Events

Time and Event Measurements with up to 3 Counters

There are 3 40 bit counters available for event measurement or event triggering. All counters are re-triggerable and can be evaluated as a part of an expression in the trigger sequences. Each counter can be programmed as a timer for timing measurements or an event counter.

3 Universal Counters - 40 Bit

• Event count 1 to 1.1 E + 12
• Cycles 1 to 1.1 E + 12
• Time 100ns to 1.3 days
• Retriggerable
• Selective release
• Trigger event when counter is zero
• Definition of time and event windows

All Counters can be read `on the fly'

Trigger Monitor

A display of the count values, the trigger values, the trigger levels and the trigger flags is available in the trigger monitor window.

Trigger Flags

Independent of the trigger levels, there are 3 freely programmable trigger flags. These flags can be read during triggering and can be used as input variables by the trigger sequencer.

48 input variables

• READ, USERDATA, OPFETCH CPU status
• PROGBREAK program breakpoint
• LINE high-level line number
• SPOT spot point
• READBREAK data read breakpoint
• WRITEBREAK data write breakpoint
• A,B,C address points
• TRIGG0,TRIGG1 bus trigger events
• TRIGGER trigger events (3 per level)
• NMI, RESET trigger events from the CPU
• FULL trace memory full
• READ, WRITTEN read or write flag
• MAIN main process
• BREAK break event
• TIMEOUT timeout signal
• SYNCH synchronous trigger
• ASYNCH asychronous trigger
• ECOUNT universal counter zero

Time Stamp

Time Stamp

The Time Stamp Unit tags each trace record with a time value. These values are absolute and sychronised with all the other time values within the TRACE32 system.

• Recording depth max. 32K
• 48 time stamp recording channels
• Resolution 25ns
• Relative channel precision 25ns
• Relative instrument precision 25ns
• Maximum measuring time 1.3 days

Performance Analysis

The statistic unit measures independently from the trace memory, the run time of specific modules of the program. Using this, the average execution time, the average execution frequency and the absolute number of calls to the entry point of a routine can be measured. Up to 63 routines can be monitored in this way.
