Microsemi SmartFusion2 - Figure 356 Fabric APB Master with MSS as Slave; Reference Documents

Fabric Interface Controller
UG0331 User Guide Revision 15.0 782
24.7.4.4 Use Model 4: Connecting a Fabric APB Master to the MSS Slave
The following figure shows APB v3.0 compliant fabric master connectivity with the MSS slaves. The APB
fabric master can access memory mapped peripherals in the MSS.

24.8 Reference Documents
Refer to the following documents for information on how to create an AHB-Lite or APB wrapper on the
custom logic connect it to the MSS system through the FIC.
Connecting User Logic to the SmartFusion Microcontroller Subsystem Application Note: This application
note explains how to create an AHB-Lite or APB wrapper on custom logic.
Building an APB3 Core for SmartFusion cSoC FPGAs Application Note: This document describes how to
create an APB wrapper interface for the user logic or IP.
TU0310: Interfacing User Logic with the Microcontroller Subsystem Tutorial: This tutorial shows you how
to interface and handle communication between the user logic in the FPGA fabric and the MSS. It also
explains the Libero SoC design software tool flow used for designing applications for the SmartFusion2
SoC FPGA family of devices.
