Description

This application note describes how to initialise the Static Random Access Memory (SRAM) blocks of Microchip RTG4 Field Programmable Gate Array (FPGA) with user data after power-up. The design for this application note uses a Large SRAM (LSRAM) block, which is initialised by an FPGA fabric master through the Advanced Microcontroller Bus Architecture Advanced Peripheral Bus interface (AMBA APB bus).

RTG4 FPGA devices have embedded SRAM blocks (LSRAM and µSRAM) in the fabric. Both LSRAM and µSRAM blocks are placed in multiple rows within the FPGA fabric, and they can be accessed through the fabric routing architecture.
