Xilinx and OrCAD work very closely to provide powerful and affordable solutions for our mutual customers. We share our technical expertise through library and interface development, the development of reference designs, synthesis optimization, integration of front-end and back-end tools, and the development of Xilinx specific documentation. 

This commitment and dedication has created the industry’s most common FPGA design flow -- OrCAD Capture or OrCAD Express to Xilinx XACT and Alliance Series. Xilinx and OrCAD will continue to work together to provide users with solutions which meet their current and future design needs. 

OrCAD Express™ is a 32-bit application for designing FPGAs and PCBs. Express allows you to mix schematics with VHDL, includes simulation, synthesis, an integrated project manager, and features to start using VHDL immediately. It provides the capability to create symbols for your FPGAs and simulate your board designs.
