resource assignment An assignment of a 
logic function in a project to a particular 
pin, logic cell, I/O cell, embedded cell, 
logic array block (LAB), embedded array 
block (EAB), row, column, or chip. This 
type of resource assignment assigns a logic 
function to a physical resource in a device.
A resource assignment can also consist of a 
clique, logic option, connected pin, timing 
requirement, or local routing assignment to 
a particular logic function in a project. This 
type of resource assignment assigns a 
compilation resource to a logic function.
row  A horizontal line of LABs connected 
by a row FastTrack Interconnect path in a 
FLEX 6000, FLEX 8000, FLEX 10K, or 
MAX 9000 device.

secondary input The Clock, Preset, 
synchronous and asynchronous Reset 
(Clear), and synchronous and 
asynchronous Load inputs to a register or a 
state machine in a design file. 
Security Bit A bit that prevents an 
EPROM- or EEPROM-based Altera device 
from being interrogated. This bit also 
prevents EPROM-based Altera devices 
from being inadvertently reprogrammed. 
The Security Bit can be turned on or off for 
each device in a project, or for the entire 
project.

Serial Bitstream File (.sbf) An ASCII file 
(with the extension .sbf) that contains the 
data for configuring a FLEX 6000, 
FLEX 8000, or FLEX 10K device with the 
BitBlaster from a system prompt. This file 
can be generated with the Combine 
Programming Files command (File menu) 
in the Compiler or the Simulator.
Serial Vector Format File (.svf)  An ASCII 
file (with the extension .svf) that stores 
programming data for programming one 
or more fixed algorithm devices in 
Automated Test Equipment (ATE)-type 
programming environments. AlteraĆs 
MAX 7000S and MAX 9000 devices can be 
programmed with SVF Files. The JTAG 
chain can contain any other device that 
complies with the IEEE 1149.1 JTAG 
specification, including FLEX 10K, 
FLEX 6000, and some FLEX 8000 devices. 
You can create SVF Files with the Create 
Jam or SVF File command (File menu) in 
the Programmer or the Compiler.
setup time On a flipflop, the setup time is 
the minimum time interval between the 
application of a signal at the input pin that 
feeds the data or Clock Enable input and a 
low-to-high transition at the input pin that 
feeds the Clock input of the flipflop or the 
Latch Enable input of the latch. 
On a latch, the setup time is the minimum 
time interval between the application of a 
signal at the input pin that feeds the data 
input of a latch and a low-to-high 
transition at the input pin that feeds the 
Latch Enable input of the latch. (Setup and 
hold time analysis for latches is available 
only for MAX 5000 devices. In other device 
families, latches are implemented using 
combinatorial logic with feedback.)
