fan-in and fan-out Fan-in refers to input 
signals that feed the input equations of a 
logic cell.
Fan-out refers to output signals that are fed 
by the output equations of a logic cell.
FastTrack Interconnect  Dedicated 
connection paths that span the entire width 
and height of a FLEX 6000, FLEX 8000, 
MAX 9000, or FLEX 10K device. These 
connection paths allow signals to travel 
between all Logic Array Blocks (LABs) in a 
device.

file icon An icon that appears in a 
MAX+PLUS II application window and 
represents a file in the current hierarchy 
tree. Double-clicking Button 1 on an icon 
opens the file that it represents. 
In the Hierarchy Display, the file icon 
shows which MAX+PLUS II editor can 
open the file. The filename extension is 
displayed at the bottom of the file icon to 
show the file type; the filename is 
displayed to the left of the file icon.
In the Compiler, the file icons show input 
and output files for the current project. 
filename The name of a design file, 
ancillary file, or other file, without the 
extension. 
A single filename can contain up to 32 
name characters, plus a 3-character 
filename extension. A full pathname plus 
filename and extension can contain up to 
128 characters. 
Because Windows 3.1 and Windows for 
Workgroups 3.11 support only 8-character 
filenames, MAX+PLUS II maps longer 
filenames on all Windows operating 
systems to 8-character filenames by 
default. These filename mappings are 
stored in the maxplus2.idx file in each 
directory that contains long filenames. 
However, you can override this behavior 
and us the built-in support for long 
filenames available in Windows NT and 
Windows 95 by setting the 
USE_WINNT_LONG_FILENAMES variable 
in the [system] section of your 
maxplus2.ini file to ON.
In the Hierarchy Display window, a 
filename, along with the file icon and 
filename extension, represents a file in the 
current hierarchy tree. 
filename extension The one, two, or three-
letter extension of a filename that follows a 
period (.).
In the Hierarchy Display window, a 
filename extension, along with the 
filename and the file icon, represents a file 
in the current hierarchy or the current 
project. 
Fit File (.fit) An ASCII file (with the 
extension .fit) generated by the Compiler 
that documents pin, logic cell, I/O cell, 
embedded cell, chip, and device 
assignments made during the last 
compilation. Assignments are recorded in 
Assignment & Configuration File (.acf) 
syntax.
The Fit File can be used for back-annotation 
and for functional testing in the Simulator 
and Programmer. To preserve assignments 
permanently, Fit File assignments can be 
back-annotated into a projectÕs ACF with 
the Back-Annotate Project command 
(Assign menu).
