GmbH MCDS User’s Guide 4 MCDS User’s Guide Version 30-Apr-2021 History ©1989-2021 Lauterbach GmbH MCDS User’s Guide 5 Introduction The MCDS (Multi-Core Debug Solution) is an on-chip trigger and trace solution from Infineon, available for the Infineon TriCore and C166/ XC2000 devices. It is used during the development stage of an embedded system for debugging, tracing, profiling, and verification. Using TRACE32, the user can set up the MCDS for performing on- and off-chip trace. Based on the generated trace recording, the user can analyze, profile, and verify the behavior of his application. Additionally, it is possible to program triggers for stopping program execution, redirecting them to device pins or to influence the trace recording, e.g. for recording only the trace data of interest. The on-chip memory used for storing the trace data can also be used for calibration, a technique that allows the dynamic overlay of code and data memory with alternate code or parameters. Calibration is not supported by Lauterbach tools. TRACE32 can be configured to cooperate with third-party tools to share resources, e.g. the on-chip memory. For using these features, a special version of the chip is required, the Emulation Device. But also some of the Product Devices include the MCDS or at least a reduced variant of the MCDS, the so-called Mini-MCDS. For related information, refer to the documentation of your device. This MCDS User’s Guide is intended to guide the TRACE32 user through the configuration of the on-chip trace, trigger and filter setup. Additionally it provides background knowledge. This User’s Guide is not intended to replace the available training manuals or the TRACE32 command references. Intended Audience The reader of this document is assumed to have basic knowledge in using TRACE32 and has gathered experience using it. Additionally specific knowledge of the architecture and the device is mandatory, see the Infineon documentation. The MCDS User’s Guide is not a replacement for the Infineon documentation of the Emulation Devices. How to read this Document It is recommended to completely read the chapters Background Information and MCDS Basic Features before reading the other ones. Developers responsible for the PLL setup are expected to read the EEC Clock System chapter to understand why the application should program the EEC clocks. It is not necessary to read this documentation completely for using the MCDS. This User’s Guide is separated into independent chapters handling different topics. These chapters can be read independently and in arbitrary order. Reading the first paragraph of a chapter gives the reader all the information to decide whether it is important for his use case or not. Some of the TRACE32 features require a deeper understanding of the MCDS and the Emulation Device implementation. The related parts and chapters of this User’s Guide are indicated to be for MCDS Expert Users only. ©1989-2021 Lauterbach GmbH MCDS User’s Guide 6 The MCDS on TriCore chips does not only support the TriCore cores, it also supports the PCP and the GTM. When referring to TriCore in general, the entire TriCore device is addressed. This includes the TriCore cores as well as the PCP or GTM cores. From the user’s point of view the MCDS implementation for C166 and XC2000 devices is identical. Within this document there is no differentiation between C166 and XC2000. Related Documents Before using the MCDS it is mandatory to know the architecture under debug. The most important information about the device can be found in the Infineon Documentation: • User’s Manual and/or Target Specification • Emulation Device Target Specification (for MCDS Expert Users) • Data-, Delta- and Errata Sheets Please contact Infineon for this documentation. This document assumes that the reader already knows how to use the TRACE32 debugger for the corresponding device. The related information can be found in the Processor Architecture Manuals: • “TriCore Debugger and Trace” (debugger_tricore.pdf)
