The Lauterbach LA-7690, LA-7862, and LA-7991 are specialized trace and debug modules within the TRACE32® platform, engineered for embedded system analysis across the complete product lifecycle—from pre-silicon RTL simulation and emulation through in-field diagnostics. These components deliver hardware-based trace recording and program flow analysis for processor-level visibility during development and troubleshooting.
The LA-7690 (PowerTrace Ethernet 512 MB) functions as a universal debug controller with integrated trace recorder, offering 512 MByte trace memory and dual connectivity via 100 Mbit Ethernet and USB 2.0. The LA-7862 is an ICD Trace Module for RISC processors, providing bus and program flow trace across 96 channels with configurable frame trace depth (64K, 128K, 256K, or 512K). The LA-7991 serves as a Preprocessor for ARM-ETM with AUTOFOCUS Flex, enhancing trace capability for ARM Embedded Trace Macrocell (ETM) and Program Trace Macrocell (PTM) interfaces.
