Italic type Internal timing parameters and variables are shown in italic type.
Examples: t
PIA
, n + 1.
Variable names are enclosed in angle brackets (< >) and shown in italic type.
Example: <file name>, <project name>.pof file.
Initial Capital Letters Keyboard keys and menu names are shown with initial capital letters. Examples:
Delete key, the Options menu.
“Subheading Title” References to sections within a document and titles of on-line help topics are
shown in quotation marks. Example: “Typographic Conventions.”
Courier type Signal and port names are shown in lowercase Courier type. Examples: data1,
tdi, input. Active-low signals are denoted by suffix n, e.g., resetn.
Anything that must be typed exactly as it appears is shown in Courier type. For
example:
c:\qdesigns\tutorial\chiptrip.gdf. Also, sections of an
actual file, such as a Report File, references to parts of files (e.g., the AHDL
keyword
SUBDESIGN), as well as logic function names (e.g., TRI) are shown in
Courier.

a., b., c., etc.
Numbered steps are used in a list of items when the sequence of the items is
important, such as the steps listed in a procedure.
■
● • Bullets are used in a list of items when the sequence of the items is not important.
v The checkmark indicates a procedure that consists of one step only.
1 The hand points to information that requires special attention.
c
The caution indicates required information that needs special consideration and
understanding and should be read prior to starting or continuing with the
procedure or process.
w
The warning indicates information that should be read prior to starting or
continuing the procedure or processes
r The angled arrow indicates you should press the Enter key.
