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.

• “Setting Up LogiBLOX on a PC”
  
  
• “Starting LogiBLOX”
  
  
• “Creating LogiBLOX Modules”
  
  
• “LogiBLOX Modules”
  
  
• “Using LogiBLOX for Schematic Designs”
  
  
• “Using LogiBLOX for HDL Designs”
  
  
• “Documentation”
  
  

NOTE

All Xilinx architectures except Virtex support LogiBLOX.

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 tutorial in the Foundation Series Quick Start Guide 1.5.
