How to Use SMC_FIC in IGLOO2 Device

This section describes how to use SMC_FIC for accessing external SDR memory. The SMC_FIC can be
enabled and configured using the System Builder in the Libero SoC design software. The System Builder
uses the CoreSDR_AXI and connects to SMC_FIC interface. The CoreSDR_AXI IP is an AXI based
SDR memory controller.The steps provided below are required to access the external SDR memory from
CoreSDR_AXI.
1. Select the HPMS External Memory, Soft Memory Controller (SMC) and HPDMA in the System
Builder - Device Features window as shown in the following image.
For details on how to launch the System Builder wizard and a detailed information on how to use it, refer
the IGLOO2 System Builder User
