IQANsimulate 4.00 released

Highlighted features

Signal generator

It is now possible to control the value of a simulation item using a signal generator. The signal generator contains a table with time/value pairs.

Import of measure file creates simulation items for each channel in the measure file that can be simulated (inputs). Values from the measure file are also imported so that you can play back a measured scenario.

Interface to other simulation software

ActiveX support implemented. Makes it possible to read and set values from external software, e.g. Microsoft Excel. There is an example file for this under the examples folder.

Remember input values and settings between simulations without having to save

Simulations can be manually saved as .isa4 files. There is also an automatically saved simulation, that stores the input values and all the settings between the simulations. When launching IQANsimulate, there is an option to select whether to use a saved simulation file or create a new one.

Keyboard shortcut for small input changes

In the simulation group view the arrows are used to select channel. Ctrl+arrows are used to change the value of the selected track bar. Added shift+ctrl+arrows to change values in raw value steps of 1 (smallest step available).

Possible to add channels to simulation group while simulating

You can now drag a channel from the functionality viewer to a simulation group without having to stop the simulation first. There is also a default simulation group, so it is not necessary to first creating a simulation group.

"Set value" function more accessible

Added a small popup below selected channel containing controls for setting values on the channel. Same method used for physical channels and for the "set value" function for stored and adjustable channels.

For more details, see release notes.


Simulate Input and Output Statuses

Chris Litwin 10 months ago in IQANsimulate updated by Thomas Moberg (System support) 4 months ago 4

Is there a way to set the statuses for inputs and outputs in IQAN Simulate 5? I know I can set COUT channels, but that option is greyed out on all other channels.

Simulate I/O diagnostics cases for HS or LS digital output on MC4X

Fredrik Lorenc 2 years ago in IQANsimulate updated by Gustav Widén (System support) 2 years ago 2

It is possible to simulate different I/O diagnostics cases for i.e. current outputs on the MC43 by left-clicking on them and selecting status. A list of different I/O faults appear for the given output. However, when trying to do the same for a HS, LS or HS/LS digital output, the "Status" option is grayed out. I find this strange as the manual for the MC4X states that there are diagnostics for these output types as well.

Inconsistent pulse counter behaviour with XC42

Pierre Fagrell 1 month ago in IQANsimulate updated by Gustav Widén (System support) 1 month ago 1

I do not know if this is a bug in the simulator or different firmware behaviour as I don't have the actual hardware to test on yet

If I put a pulse counter on an MC42 and increase with 1 each cycle it will show as 1,2,3 etc in the simulator when Accumulate=Yes

If I point with the mouse pointer the popup shows similar values in both fields

The application seems to use the accumulated value as expected

If I put a pulse counter on an XC42 and increase with 1 each cycle it will show as 1,1,1 etc in the simulator when Accumulate=Yes

If I point with the mouse pointer the popup shows both the incremented and accumulated value

The application seems to use the incremented value

In both tests I have the setting "Full Value Range=Off".

If I turn it on XC42 behaviour changes.

Simulator crashes after deleting input channel

Pierre Fagrell 2 months ago in IQANsimulate updated by Gustav Widén (System support) 2 months ago 1

IQANsimulator 6.00 will crash if you delete an input channel in IQANdesign that is already in a simulation group.

Steps to reproduce:

  1. Create an application with MD4 + MC42
  2. Add a digital IN PU to MC42 C:13
  3. Simulate application and add this digital input to a simulation group
  4. Save and quit the simulator
  5. Delete the input from iqandesign
  6. Click run to start the simulator again

Simulator crashes with following message:

Control channel selector menu outside screen

Pierre Fagrell 2 months ago in IQANsimulate updated by Gustav Widén (System support) 2 months ago 1

In most situations the menu for selecting a control channel is aligned outside the screen, making it impossible to select all channels on a regular 1080p monitor.

If I have the simulator at the bottom half of a 4k monitor or fullscreen on a regular monitor it aligns incorrectly.

If I have the simulator fullscreen or aligned to the top of a 4k monitor it works fine.


Display refresh issue using moving images

Olivier 5 months ago in IQANsimulate updated 5 months ago 1

Hi, I got some problem on image refreshing while moving. Actually we are using the image selector at the same time than the moving position.Please look at the rolling menu display in this video.


We will try to "Hide" and "Show" these moving pictures during the transition because it seams the only way we can "refresh" the display and hide bugs, but if you have a more elegant solution please advise !


Starting and stopping simulate

Ed Schippers 9 months ago in IQANsimulate updated by Gustav Widén (System support) 9 months ago 1

Starting and restarting of a simulation takes a lot of time and after every (re)start it starts in the same view so when you are working on large projects you need to a lot of clicking before you reach the part that you are testing. this is particularly annoying when testing  functions that run only just after boot up.

It would be nice if there was a function that you could do a restart without stopping the simulation and/or a or a function that when a simulation is started the program it stays in a pre- operational state so that you can navigate to the part of the program that you are testing and then start the program simulation. 


Image on camera while simulating

Joshua 1 year ago in IQANsimulate 0

Looking for a way to display an image on the screen in place of the missing camera feed while simulating.  Trying to record screen activity to show during presentations and having the missing cam feed looks bad.
