1.7.2. Design flow

The STM is delivered as synthesizable RTL. Before it can be used in a product, it must be integrated and implemented. Implementation and integration choices affect the behavior and features of the STM. 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 macrocell.

Configuration inputs

The integrator configures some features of the STM 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 the STM by programming particular values into registers. This affects the behavior of the STM.
