New Features
3-9
Sine Wave Block Enhancements
The Sine Wave block now supports a bias factor that eliminates the need to
sum with a Constant block. The Sine Wave block also has a new computational
mode. This mode (called sample-based) eliminates the dependence on absolute
time.
Enhanced Flip-Flop Blocks
Simulink Extras (simulink_extras.mdl) contains a set flip-flop blocks. These
blocks now use the new triggered subsystem latching semantics. In addition,
the S-R Flip-Flop block now models a physical
NOR gate (i.e., S=1, R=1 => Q=0,
Q!=0, the undefined state).
Additional Data Type Support
The Discrete-Time Integrator and Rounding Function blocks now handle
single as well as double values. The Transport Delay, Unit Delay, Variable
Transport Delay, Memory, Merge, and Outport blocks can specify nonzero
initial conditions when operating on fixed-point signals.
Simulink Block Library Reorganization
The Simulink Block Library contains a new Subsystems sublibrary. The new
library contains most of the new control flow blocks as well as subsystem and
subsystem-related blocks that used to reside in the Signals & Systems library.
The subsystems in the new library each contain the minimum set of blocks
needed to create a functioning subsystem, e.g., an input port and an output
port.
Scope Enhancements
The Scope block includes the following enhancements:
•A floating version of the Scope added to the Sinks block library
•Floating Scope saves the signals selected for display in the model file
•The Scope’s toolbar buttons for toggling between floating/nonfloating mode,
restoring saved axes, locking/unlocking axes, and displaying the
Signal
Selector
