Introduction
The Altera
®
 Quartus
® 
II design software provides a complete, multiplatform 
design environment that easily adapts to your specific design needs. It is a 
comprehensive environment for system-on-a-programmable-chip (SOPC) 
design. The Quartus II software includes solutions for all phases of FPGA 
and CPLD design. See Figure 1 for an illustration of the Quartus II design 
flow.
Figure 1. Quartus II Design Flow
In addition, the Quartus II software allows you to use the Quartus II 
graphical user interface, EDA tool interface, or command-line interface for 
each phase of the design flow. You can use one of these interfaces for the 
entire flow, or you can use different options at different phases of the design 
flow. This chapter explains the options that are available for each of the 
design flows, as well as design methodologies. The remaining chapters in 
this manual describe individual stages of the design flow in more detail.
