Mentor Graphics Interface: Documentation 

Design Flow

    These are schematic and schematic with VHDL macro tutorials designed to be used with Mentor C.2 and Xilinx 2.1i. This tutorial will take you through setting up the tutorial , the design flow, completing the Calc design, and using the Xilinx Design Manager. It will also lead you through a pre-2.1i functional simulation as well as a post-PAR Timing simulation. This tutorial is based on the older Calc tutorial.
