Using the Altera Schematic Express (sch_exprss) Utility
Once you have created a Design Architect schematic, you can use the Altera Schematic Express utility (sch_exprss) to generate a Design Viewpoint Editor (DVE) viewpoint and an EDIF netlist file from the schematic; process the EDIF Input File (.edf) with the MAX+PLUS® II software to generate an EDIF Output File (.edo); process the EDIF Output File with ENRead and DVE software; and generate an altera_asim viewpoint for simulation. The sch_exprss utility creates all necessary subdirectories and copies all of the files to the correct locations.
To use the sch_exprss utility, follow these steps:
Be sure to set up the working environment correctly, as described in Setting Up the MAX+PLUS II/Mentor Graphics/Exemplar Logic Working Environment. Create a Design Architect schematic that follows the guidelines described in Creating Design Architect Schematics for Use with MAX+PLUS II Software. Select your project's folder, press Button 3, and choose Open sch_exprss from the Mentor Graphics Navigator window to start the Altera Schematic Express tool. Specify settings for the Input Schematic, Altera Device Family, MAX+PLUS II Synthesis Style, Process Direction, and Verbose options in the sch_exprss dialog box and choose OK to generate the altera_asim file for simulation with QuickSim II software. If necessary, correct any errors in the Design Architect schematic design file and recompile the project. The sch_exprss utility generates the altera_asim viewpoint in the appropriate directory. Simulate your project, as described in Performing a Timing Simulation with DVE & QuickSim II Software.
