Module	Enhancements
CSharpAPI
SimWBCSharpAPI.dll	Added support for FMU model parsing Added support to allow concurrent connections to multiple hosts. Incompatibility Consideration: Existing code will need to be modified such that an instance of the simwbClient will need to be created before any of the methods can be invoked. For instance, existing code of the following form: simwbClient.connect("host"); simwbClient.login(username,passwd); Will need to be refactored as follows: simwbClient host = new simwbClient(); host.connect("host"); host.login(username,passwd);
User Models	Added three new tests demonstrating various methods of accessing RTDB variables with Fortran modules that are linked into a C-based User Model. rtdemo1_test_fort_api uses C API calls to read/write RTDB variables, rtdemo1_test_fort_flat converts the RTDB into a flat namespace whose variables are directly accessed in Fortran, and rtdemo1_test_fort_struct converts the RTDB into a structured namespace whose variables are directly accessed in Fortran.
FMU/FMIL	Added support for automatic recompilation of OpenMP FMUs (Dymola only)
I/O Tasks	NETIO Behavior change consideration: Added support for shutdown values. Now, when the test stops, the NETIO output will ramp down to shutdown value set in Initial Conditions tab. All existing tests that uses NETIO will have this enabled by default. If you do not want the NETIO to ramp down from the last value, you can disable shutdown values in the Initial Conditions tab. canasyncio Behavior change consideration: Added support for shutdown values. Now, when the test stops, the CAN output will ramp down to shutdown value set in Initial Conditions tab. All existing tests that uses CAN will have this enabled by default. If you do not want the CAN to ramp down from the last value, you can disable shutdown values in the Initial Conditions tab. Input thread is run on a timer to minimize jitter and not on a sleep. Output messages are sorted so that high frequency messages are output first. canout Behavior change consideration: Added support for shutdown values. Now, when the test stops, the CAN output will ramp down to shutdown value set in Initial Conditions tab. All existing tests that uses CAN will have this enabled by default. If you do not want the CAN to ramp down from the last value, you can disable shutdown values in the Initial Conditions tab. cpmfio Added 20V bipolar output option for Differential mode. ecatmaster (EtherLab) Modified <code>/usr/local/ccursim/etherlab/install_ecatmaster.sh</code> to install driver in /opt/etherlab. ixxatasyncio Behavior change consideration: Added support for shutdown values. Now, when the test stops, the IXXAT CAN output will ramp down to shutdown value set in Initial Conditions tab. All existing tests that uses IXXAT CAN will have this enabled by default. If you do not want the IXXAT CAN to ramp down from the last value, you can disable shutdown values in the Initial Conditions tab. Support for 12 boards. Multiple cores should be specified when running with more than 5 boards. 3 Cores is recommended. Irq affinity for all boards set to 1 core as well as all API threads to same core. 1 separate core for input thread and another core for output thread. Input thread is run on a timer to minimize jitter and not on a sleep. Output messages are sorted so that high frequency messages are output first. ixxatout Behavior change consideration: Added support for shutdown values. Now, when the test stops, the IXXAT CAN output will ramp down to shutdown value set in Initial Conditions tab. All existing tests that uses IXXAT CAN will have this enabled by default. If you do not want the IXXAT CAN to ramp down from the last value, you can disable shutdown values in the Initial Conditions tab. netioout Added support for shutdown values.

You must manually call savepath to add MLToolkit directories to your MATLAB path after MLToolkit installation.
Python API/ASAM Support	Captures can now define a CSV or MDF 4.0 writer during a Fetch. The writer is automatically invoked when the capture result is returned. MDF 4.0 writers require the asammdf python package (and it's dependencies). Two boolean attributes have been added to Captures: StartByTimeout and StopByTimeout.
Python API/PYToolkit	Added support for python initialization scripts.
SimWB API / Client API	Removed crypt reference from the library. It is no longer needed to link against -lcrypt when using libccur_SIMClient.so.

Release 2017.1-0 (02/21/2017)

Module	Enhancements
CSharpAPI
SimWBCSharpAPI.dll	Add support for API call putFile that sends a local file to SimWB host.
I/O Tasks	CP_UEGO Add support for UEGO board. Dolphin IX Add support for local/remote segments. FDX Added support for FDX protocol.
MATLAB/Simulink	Demos Added new demo model "ccur_split_buses" to demonstrate the Split Model feature with a model that contains buses. MLToolkit Clicking Connect loads saved settings in the GUI, including the Project in the Simulator Access tab, and the RTDB name and regular expression strings in the RTDB Creator and Code Generator panes. RTW Using the Generic Real-Time (GRT) system target file (STF), grt.tlc, for code generation instead of a custom system target file (simwb_grt.tlc or simwb_ert.tlc). This change allows us to better leverage the generated code for a variety of features. The "System Target File" radio button has been removed from the MLToolkit GUI and simwbPrefsRW now returns 'grt.tlc' as the default value for the codegeneratoroptions.systemtargetfile field. For models being used with MLToolkit for the first time, GRT is used by default. For models that have been already used with MLToolkit, the codegeneratoroptions.systemtargetfile field may be set to simwb_grt.tlc in the preferences file. You can continue using this setting for code generation or change it to grt.tlc. If the STF is simwb_grt.tlc, the simwb_rt.tmf template make file (TMF) is used. However, if the STF is set to grt.tlc, the simwb_grt.tmf file is used. The two TMF files are marginally different, but the distinction allows you to port forward any changes made to simwb_rt.tmf or simwb_grt.tlc. To modify the MLToolkit preferences file for a file, use the editsimwbpref command. For more information about using this command, type help editsimwbpref at the MATLAB command prompt.
SimWB Core	cfgsrv SIMulation Workbench major version number now reflects the year of the release. That is, SimWB version numbers will now use the convention: YEAR.MINOR-REVISION. Here, YEAR is the four-digit numerical representation of the year of release (for example, 2017), MINOR is the minor version number, and REVISION is the revision number.

If the user is running a simulation only license, the user will only be able to create simulation mode sessions.

Release 7.9-0 (12/16/2016)

Module	Enhancements
SimWB Core	RTDB The behavior of AIO, DIO, STRIO points that are mapped to hardware is unchanged. For example, a mapped AIO point behaves as an AI if mapped to an input device and it behaves as an AO if it is mapped to an output device instead. However, unmapped AIO, DIO, and STRIO points now behave as output variables when you attempt to set their CVT values using the RT-Viewer. For example, when you use the RT-Viewer to set the CVT value of an AIO point, only the ALT value is updated, same as if it were an AO point. This change was made for logging reasons. cfgsrv Added support for new CAN FD board IXXAT. Added support for UEGO board. Added transceiver amplitude and RT response time to the channel properties in 1553. scheduler We now support 40 model programs in the SimWB test for the purpose of RT Viewer stats.

This option controls how the CAN ID appears in the name of RTDB variable that is created for a relevant signal (hexadecimal or decimal). The option name is now consistent with the corresponding option in the Control Center's CAN DBC Import I/O Mapping > DBC File pane. RTW A file called ModelOriginInfo is now included in the RTW.Sources folder for a model on the real-time host. This file specifies the location of the model on the client machine, user name and IP address that uploaded the model, RTDB/code generation options, etc. Use this file to retrace the origin of a model on the real-time host machine. client module Added help for select API calls used to generate the RTDB and SimWB-compliant code for a model. For example, execute "help simwb.rtobj.createRTDB" at the MATLAB Command Prompt to access syntax information.

MATLAB/Simulink	Ignore FromWs block in Signal Builder Blocks during RTDB creation and check compliance. Convert sample time of Inf to -1 for const blocks since SimWB does not under stand Inf. Add underscore in front of subsystem and block names to make them into a C compliant structure. This take care of the issue when block names are C keywords like double, const etc.
SimWB API	Change schedule TX of CAN messages from board implementation/API to software timing as in afdxasyncio and arinc429asyncio. All corresponding API calls have been added to allow for control of TX rates/modes, etc.
SimWB Core	Add service call gethardwarevars to get the list of internal variables from the selected RTDB. The hardwarerecord.db file is read and internal variable names are generated from it.

Release 5.0-1 (05/11/2012)

Module	Enhancements
Control Center	New navigation with global toolbar, global command tabs, and local toolbars. New session start/stop/pause buttons in the global toolbar. New improved tab panels for easier workflow. Ability to display ALT value in the DLViewer plot. Improved display speed when displaying a test run with many different rates. Add refresh button to reload the list of RTDB's. Add support for default value for array items. Add refresh button to reload the list of tests.
Data logger	Improved tag creation heuristics always result in a tag. -X option added to specify extracted items on the command line. -M option added to list only the tag table. -l option added to make communication of messages to SimWB optional (now off by default, instead of on). Meta information will now be sent to stdout instead of stderr.
I/O Tasks	PAS2080 initialization of pulse window latch now deferred one cycle for more accuracy. Toothed wheel bias handling improved to avoid possible hang.
MATLAB/Simulink	Enhanced support for nested model referenced models. Support added for non-virtual buses in MATLAB R2010a and later. Support added for propagating constant block values as RTDB variable default values for Constant blocks mapping to RTDB variables in R2010a and later. New hierarchical structure for RTDB variables created from the SimWB Toolkit. New regular expression support for automatic RTDB creation.
SimWB Core	Support added for default value of array items. New generic multirate scheduler added to SimWB.
