1.7 Product documentation and design flow
This section describes the CCN-502 books and how they relate to the design flow.
documentation is as follows:
- Technical Reference Manual
The Technical Reference Manual (TRM) describes the
functionality and the effects of functional options on the behavior of the CCN-502. It is required at all
stages of the design flow. The choices you make in the design flow can mean that some
behavior described in the TRM is not relevant. If you are programming the CCN-502 then contact:
- Configuration and Sign-off Guide
The Configuration and Sign-off Guide (CSG) describes:
- The available build configuration options and related issues in
- How to configure the Register Transfer
Level (RTL) with the build configuration options.
- How to integrate RAM arrays.
- How to run test patterns.
- The processes to sign off the configured design.
The ARM product deliverables include reference scripts and information about using
them to implement your design. Reference methodology flows supplied by ARM are example
reference implementations. Contact your EDA vendor for EDA tool support.
The CSG is a confidential book that is only available to licensees.
- Integration Manual
The Integration Manual (IM) describes how to integrate the CCN-502 into an SoC. It includes a description of the pins that the
integrator must tie off to configure the macrocell for the required integration. Some
of the integration is affected by the configuration options used when implementing the
The IM is a confidential book that is only available to licensees.
The CCN-502 is delivered as synthesizable RTL. Before it can be used
in a product, it must go through the following processes:
- The implementer configures and synthesizes the RTL to produce a hard
macrocell. This includes integrating RAMs into the design.
- The integrator connects the implemented design into an 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 the CCN-502, and tests the required
- Can be performed by a different party.
- Can include implementation and integration choices that affect the
behavior and features of the CCN-502.
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 CCN-502 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 CCN-502 by programming particular
values into registers. This affects the behavior of the CCN-502.
Note: 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.
