The Lauterbach LA-7693 and LA-7992 are precision debugging and trace analysis tools for embedded systems. The LA-7693 (PowerTrace II 2 Gigabyte) is a legacy trace port recorder delivering 2 Gigabyte of trace memory with streaming rates up to 180 MByte/s. The LA-7992 is a parallel preprocessor for ARM/Cortex Embedded Trace Macrocell (ETM) and Program Trace Macrocell (PTM) incorporating AUTOFOCUS self-calibration technology. Both integrate into the TRACE32 debugging environment, enabling real-time tracing, code coverage analysis, and multicore debugging across diverse target architectures.
Technical Specifications
LA-7693 (PowerTrace II 2 Gigabyte)
• Trace Memory: 2 Gigabyte
• Streaming Rate: Up to 180 MByte/s
• Expandable with Logic Analyzer Probe (LA-7945) or Analog Probe (LA-7949)
• Requires PowerDebug X51/X50, PowerDebug PRO, or PowerDebug II
• Requires suitable trace preprocessor or Nexus Adapter
LA-7992 (ARM-ETM/AUTOFOCUS II 600 Flex Preprocessor)
• Traceport Bandwidth: 9.6 Gbps (at 300 MHz clock speed, DDR)
• Operating Voltage: 1.2 V to 3.3 V
• Connectorization: 2×38 pin MICTOR connectors
• Supports all ETM modes
• Requires PowerTrace II/III, PowerTrace PX, or PowerTrace/Ethernet Version 6 or higher
– Key Features
• AUTOFOCUS self-calibration technology for accurate parallel ETM/PTM preprocessing
• Support for C, C++, JAVA, Pascal, Modula2, PEARL, and ADA compiler output
• High-level and assembly language debugging with simultaneous window support
• Hierarchical symbol database with C++ signature demangling
• Multicore debugging capability
• Variable display and modification across all high-level language types
– Typical Applications
• Real-time embedded system trace capture and analysis
• ARM/Cortex processor debugging with ETM/PTM traceport monitoring
• Code coverage analysis and performance optimization
