A1.7 Design process

ETM-M33 is delivered as synthesizable RTL. Before it can be used in a product, it must go through the following process:

For MCUs, often a single design team integrates the processor before synthesizing the complete design. Alternatively, the team can synthesize the processor on its own or partially integrated, to produce a hard macrocell. The hard macrocell is then integrated, possibly by a separate team, which might include integrating RAMs into the design.
The integrator connects the implemented design into a SoC. This includes connecting it to a memory system and peripherals.
This is the last process. The system programmer develops the software required to configure and initialize ETM-M33, and tests the required application software.

Each stage of the process:

  • Can be performed by a different party.
  • Can include implementation and integration choices that affect the ETM-M33 behavior and features.

The operation of the final device depends on:

Build configuration
The implementer chooses the options that affect how the RTL source files are pre-processed. These options usually include or exclude logic that affects one or more of the area, maximum frequency, and features of the resulting design.
Configuration inputs
The integrator configures some of the ETM-M33 features by tying inputs to specific values. These configurations affect the start-up behavior before any software configuration is made. They can also limit the options available to the software.
Software configuration

The programmer configures ETM-M33 by programming particular values into registers. This affects the ETM-M33 behavior.


This manual refers to implementation defined features that are applicable to build configuration options. Reference to a feature that is included means that the appropriate build and pin configuration options are selected. Reference to an enabled feature means one that has also been configured by software.
