If you are upgrading from a software version other than the m ost recent one,
review the current release notes and all interim versions. For example, when
you upg rade from V1.0 to V1.2, review the release notes for V1.1 and V1.2.

Version Compatibility Con si derations
When a new feature or change introduces a reported incompatibility between
versions, the Compatibility Considerations subsection explains the
impact.
Compatibility issues reported after the product release appear under Bug
Reports at The MathWorks™ Web site. Bug fixes can sometimes result
in incompatibilities, so review the fixed bugs in Bug Reports for any
compatibility impact.
Fixed Bugs and Known Problems
The MathWorks offers a user-searchable Bug Reports database so you can
view Bug Reports. The development team updates this database at release
time and as more information becomes available. Bug Reports include
provisions for any known workarounds or file replacem ents. Information is
available for bugs existing in or fixed in Release 14SP2 or later. Information
is not avail able for all bugs in earlier release s.

hardware required to use EDA Simulator Link software with the current
release.
Enable Direct Feedthrough for HDL Designs with Pure
Combinational Datapaths
The HDL Cosimulation block now supports direct feedthrough,whichmeans
that the output is controlled directly by the value of an input port. The input
valuechangepropagatestotheoutputportsinzerotime,thuseliminating
one output-sample delay for HDL designs with pure combinational logic
datapaths. This feature eliminates the need to modify the test bench portion
of Simulink to compensate for cosimulation block delay.
New Functions for HDL Simulator Client
Communication
A new function, notifyMatlabServer, allows you to sen d HDL simulator
event and process IDs to MATLAB server. Another new function,
waitForHdlClient, waits to begin proces sing until the specified event ID is
obtained or a user-specified time-out occurs.
Batch, CLI, and GUI Mode Support Added for
Cosimulation with HDL Simulators
You can execute cosimulation in batch mode for background proces sing or CLI
mode for ease in debugging.
Use Same MATLAB Function for Multiple HDL
Instances
This release adds a new argument, use_instance_obj, to the MATLAB
functions
tnext, tnow, and portinfo arguments of the MATLAB function definition with
an HDL instance object passed to the function as an argument. With this
feature,

Version 3.1 (R2010a) EDA Simulator Link™
• You can use the same MATLAB function to represent behavior for different
instances of the same module in HDL without need to create one-off
wrapper functions.
• You no longer need special "portinfo" argument on first invocation.
• You no l onge r need to use persistent or global variables.
• You receive better feedback and protections on reading/writing of signals.
• You can use object fields to identify the instance path and whether the call
comes from a component or test bench function.
• You can use the field argument to pass user-defined arguments from the
matlabcp or matlabtb instantiation on the HDL side to the function
callbacks.
The new argument, -use_instance_obj, is identical for both
matlabtb. See the Function Reference for matlabcp and matlabtb for
instructions in using this new function argument.

Generating Transaction Level Models for Use with
Virtual Platforms

• Generation of standalone SystemC test bench for generated TLM 2.0

Limitations The design under generation must contain both inputs and
outputs. Designs that only have inputs or only have outputs (sink or source
blocks) are not supported in this release. If you do not include both, EDA
Simulator Link displays an error message and discontinues code generation.
