Quartus II is a software tool produced by Altera for analysis and synthesis of HDL designs, which enables the developer to compile their designs, perform timing analysis, examine RTL diagrams, simulate a design's reaction to different stimuli, and configure the target device with the programmer. The Web Edition is a free version of Quartus II that can be downloaded or delivered by mail for free. This edition provided compilation and programming for a limited number of Altera devices. The low-cost Cyclone family of FPGAs is fully supported by this edition, as well as the MAX family of CPLDs, meaning small developers.
