Creating a New Project

a project called

demo_design with the default revision name of

demo_design and an unspecified target device family or part, the

following Tcl command is executed:

tcl> project_new demo_design

Creating a new project creates a quartus settings file (QSF) and a

Quartus II Project file (QPF) in the current directory. In addition, a db

subdirectory is created that is used to store Quartus II database files. In

the case of the

demo_design project example, the following files are

created in the project directory:

demo_design.qpf

demo_design.qsf

db/

demo_design.db_info

Opening a Project

The project created automatically opens when you use the project_new

command. In future Quartus II sessions, or if you close the project, you

must open the project with the Tcl command: project_open. The syntax

for the

project_open command is:

tcl> project_open [-current_revision] \

[-revision <revision_name>] <project_name>

For example, to open the default revision of project

demo_design,

execute the following Tcl command:

tcl> project_open demo_design

It is a good practice to have consistent names for the Stratix II

and HardCopy II revisions of your project. This makes it easy to

identify which revision is which. For example, naming your

revisions projectname_fpga and projectname_hcii would help you

easily identify which revision is the Stratix II revision, and

which is the HardCopy II revision.

Closing a Project

Before ending a Quartus II project session, it is good practice to close the

Quartus II project using the project_close command. This ensures that

any changes you have made to your project are written to the Quartus II

QSF file. The syntax for the project_close command is:

tcl> project_close [-dont_export_assignments]
