Spartan-6 FPGA Design Assistant - Designing block RAM in Spartan-6 FPGAs

Description

This Answer Record provides information on how to use the block RAM in the Spartan-6 FPGA fabric.

NOTE: This Answer Record is part of the XilinxSpartan-6 FPGA Solution Center (Xilinx Answer 44744).The XilinxSpartan-6 FPGASolution Center is available to address all questions related toSpartan-6 devices.Whether you are starting a new design withSpartan-6 FPGA or troubleshooting a problem, use theSpartan-6 FPGA Solution Center to guide you to the right information.

Solution

The built-in block RAM primitive in the Spartan-6 FPGA can be used to implement RAMs, ROMs, and FIFO blocks for a design.The block RAMis optimized for performance and allows you to implementa RAM, ROM, or FIFO block in a design without requiring large amounts of fabric resources from slice logic.

The Spartan-6 FPGABlock RAM ResourcesUser Guide (UG383)provides additional details on the block RAM. It is recommended that you read through the user guide to familiarize yourself with its use and howit can be used in your design:
