Dear Forum
I have a problem with running my FPGA VI on the development Comupter with simulated I/O
I Created a testbench as described in
http://zone.ni.com/reference/en-XX/help/371599D-01/lvfpgaconcepts/test_bench_tutorial/
This works fine. I can read an write the I/O Nodes
But when I insert a read/write control node (from the FPGA interface palette) into my Host-VI to directly write a value to a Control on my FPGA VI, i get the error -61499
The error happens in the VI on my Hostcomputer ad the message is:
An internal software error on LabView FPGA Module has occurred. Please contact NI technical support.
The error does not happen, if I remove the read/write control, or if I dont call it.
The error does not happen, if I compile the fpga-vi and let it run on my fpga hardware. It happens only in the simulated mode.
The error happens in the simulated mode when i use the testbench for simulating input Signals, it also happnes, when I use random Input Signals.
It seems that the error does not happen during compilation. The simulated VI runs and the error happens, only when I call the read/write control.
Can anybody help me?
I appreciate every suggestion
Thanks
David
Solved! Go to Solution.

Is it possible, that i have to control the read/write nodes also in the testbench?
I ayctually dont think so, but im not sure.

Ok, the problem is solved, thanks to ni support who helped me:
The solution is, not to have spaces and end of lines in the names of frontpannel elements.
In simulated mode, a host-vi has problems to access frontpannel elements of the fpga-vi with the read/write node if the frontpanel elements have special characters.
