We start by reviewing the steps it takes to invoke Precision Synthesis and start the synthesis process. As seen in Module 2, you can invoke the Precision Synthesis GUI with the precision command from the Windows Command Line or Unix shell, or you can create a shortcut on the desktop. Also, you can invoke Precision Synthesis from the shell using the precision -shell command. This causes Precision Synthesis to be invoked in non-GUI command-line mode in which you can source a Tcl script or interactively enter commands from the shell. When you are finished, use the quit command to exit from the program.

After invoking Precision Synthesis, you will start by setting up your working directory. All the project files will be located under this specified location.

After you have selected your working directory, you will need to select the technology that will be used during synthesis.

Finally you have to add the design input files. You can add input files such as VHDL, Verilog, and EDIF to the list of input files of your project.
Now you are almost ready to start the synthesis process.
