The cycle of laboratory work on the development by students of methods of designing specialized ultra-large integrated circuits (SBIS) based on FPGAs and in the form of custom chips was prepared by the staff of the Department of Design of Electronic Means (CES) of the Taganrog State Radio Technical University (TRTU) . The paper describes the information necessary to describe the projects of specialized SBIS in the VHDL language in the Renoir CAD subsystem FPGA Advantage Mentor Graphics. Features of Renoir subsystem, graphical interface, file organization of projects, routes of synthesis and generation of VHDL-descriptions, features of work with VHDL-libraries, connection of Renoir subsystem with Model. subsystems are described. Sim and Leonardo Spectrum CAD FPGA Advantage.
