1 In the UNIX workstation 
environment, filenames and hence 
subdesign names are case-sensitive.
sum-of-products A Boolean expression is 
said to be in sum-of-products form if it 
consists of product terms combined with 
the OR operator.
super-project and sub-project A super-
project consists of a top-level design file 
that contains symbols or instances 
representing multiple, individual projects.
A sub-project is any individual project that 
serves as part of a super-project. You can 
use any super-project as a sub-project in a 
higher-level super-project.
SVF File see Serial Vector Format File.
Symbol File (.sym) A graphic file (with the 
extension .sym) created by the Symbol 
Editor or the Compiler Netlist Extractor 
module of the Compiler. This file 
represents a design file (i.e., megafunction 
or macrofunction) or MAX+PLUS II 
primitive with the same name and can be 
used in Graphic Design Files (.gdf).
When the CompilerÕs Linked SNF 
Extractor module is turned on, a symbol in 
a Graphic Editor file represents a Simulator 
Netlist File (.snf), rather than a design file, 
during compilation.
symbol ID number or net ID number A 
number that uniquely identifies every 
node and symbol in a design file. 
In the Graphic Editor, this number appears 
inside the bottom left corner of a symbol 
and reflects the order in which symbols are 
entered in a Graphic Editor file. In other 
types of design files, the Compiler assigns 
ID numbers to nodes when the project is 
compiled. In the Hierarchy Display 
window, the name of each lower-level 
design file is appended with a colon (:) 
plus the ID number or an AHDL,VHDL, or 
Verilog HDL mega- or macrofunction 
instance name.
T
Table File (.tbl) An ASCII file (with the 
extension .tbl) that contains a tabular-
format list of all input vectors and output 
logic levels in the current Vector File (.vec) 
or Simulator Channel File (.scf). The Table 
File can be generated in the Simulator or 
Waveform Editor. 
Tabular Text File (.ttf) An ASCII text file in 
tabular format (with the extension .ttf) 
containing configuration data for 
FLEX 6000, FLEX 8000, and FLEX 10K 
devices. A TTF contains the decimal 
equivalent of a Raw Binary File (.rbf).
The MAX+PLUS II Compiler automatically 
creates TTFs containing configuration data 
for the sequential Passive Parallel 
Synchronous (PPS), Passive Parallel 
Asynchronous (PPA), and Passive Serial 
(PS) configuration schemes for FLEX 8000 
devices, the PS configuration scheme for 
FLEX 10K devices, and the PS and Passive 
Serial Asynchronous (PSA) configuration 
schemes for FLEX 6000.
After compilation, you can also create TTFs 
that support other configuration schemes 
for FLEX 6000, FLEX 8000, and FLEX 10K 
devices.
t
CO
 (Clock to output delay) The time 
required to obtain a valid output at an 
output pin that is fed by a register after a 
Clock signal transition on an input pin that
