The Block Memory Generator LogiCORE™ IP core automates the creation of resource and power optimized block memories for Xilinx® FPGAs. Available through the (add ref to Vivado™) ISE® Design Suite CORE Generator™ System, the core enables users to create block memory functions to suit a variety of requirements. Built-in knowledge about Xilinx device architectures allow it to leverage specialized FPGA architectural features to create the most compact, high performance or low power solution.
A Migration Kit is available to automate the migration to latest version of the core.
Key features are:
- Choice of Native Interface, AXI, or AXI4-Lite
- Example Design helps you get up and running quickly
- Native interface core
- Generates Single-Port RAM, Simple Dual-Port RAM, True Dual-Port RAM, Single-Port ROM, or Dual-Port ROM

Documentation
The COTS version v7.3 is the baseline from which the DO-254 Block Memory Generator 1.00a comes from. Logicircuit applies the DO-254 lifecycle to this COTS version. As a result of this DO-254 process, the source code will be modified with the goal of achieving 100% code coverage, and the resulting code will be named DO-254 Block Memory Generator 1.00a. Below are links to the Xilinx® Product Data for the version that was used as the basis, and the Logicircuit Data Sheet of the resulting DO-254 product.
