1.7 Product documentation and design flow

This section describes the CCN-502 books and how they relate to the design flow.

Documentation

The CCN-502 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:

  • The implementer to determine:

    • The build configuration of the implementation.
    • What integration, if any, was performed before implementing the CCN-502.
  • The integrator to determine the pin configuration of the device that you are using.
Configuration and Sign-off Guide

The Configuration and Sign-off Guide (CSG) describes:

  • The available build configuration options and related issues in selecting them.
  • 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 CCN-502.

The IM is a confidential book that is only available to licensees.

Design flow

The CCN-502 is delivered as synthesizable RTL. Before it can be used in a product, it must go through the following processes:

Implementation
The implementer configures and synthesizes the RTL to produce a hard macrocell. This includes integrating RAMs into the design.
Integration
The integrator connects the implemented design into an SoC. This includes connecting it to a memory system and peripherals.
Programming
This is the last process. The system programmer develops the software required to configure and initialize the CCN-502, and tests the required application software.

Each process:

  • 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.
