LogiBLOX

LogiBLOX is an on-screen design tool for creating high-level modules such as counters, shift registers, and multiplexers for FPGA and CPLD designs. LogiBLOX includes both a library of generic modules and a set of tools for customizing these modules. LogiBLOX modules are pre-optimized to take advantage of Xilinx architectural features such as Fast Carry Logic for arithmetic functions and on-chip RAM for dual-port and synchronous RAM. With LogiBLOX, high-level LogiBLOX modules that will fit into your schematic-based design or HDL-based design can be created and processed.

This chapter contains the following sections.

Note: LogiBLOX supports all Xilinx architectures except Virtex.

For information about instantiating LogiBLOX into designs, refer to the “Schematic Designs With Instantiated LogiBLOX Modules” section of the “Design Methodologies - Schematic Flow” chapter and the“HDL Designs with Black Box Instantiation” section of the “Design Methodologies - HDL Flow” chapter.

For an example of how to use a LogiBLOX module, refer to the in-depth Foundation Watch tutorial available via the Xilinx web site at http://support.xilinx.com.
