set an arbitrary input to check if code is working

[kwaris]

Hi,

I am dragging and dropping inputs from my project explorer to fpga vi. There is no crio though I selected new devices rather than existing devices while setting up the project. In order to complete my code and then plug in crio , Is it possible to set an arbitrary input to my dragged and dropped inputs, develop all code and then plug in crio.

One way is to click right click FPGA>>execute vi on>> development computer with simulated i/o. This indeed save development time as one doesn't have to compile fpga with every change. But I am after setting the inputs to lets say a digital pulse signal than develop all code on the basis of this digital pulse signal and then plug in real crio and sensors.

Many thanks for help

Best regards

You need right-click on the FPGA target, goto Properties and then choose Debugging. In the Debugging Properties page, select Use Custom VI for FPGA I/O  from the Execute VI on Development Computer with Simulated I/O  pull-down menu. Have a look at:

Tutorial: Creating Test Benches (FPGA Module)

and go to the Testing the FPGA VI on the Development Computer with a Custom VI section.

This seems pretty useful. The test bench I would like to create is digital signal on FPGA I/O. In custom vi there're two controls data from node input terminal and data to node output terminal.

Shall I replace the data from node input terminal with create signal pallete as shown in attachment. If so, what is the replacement for data to node output terminal.

Many thanks! I dont need to test the output tho. I am only creating front panels.

Best regards

Hi,

I got through the first problem- created custom vi, obtained digital signal from create signal function, ran vi and got digital signal- Great !!

When I went back to fpga, set it to get signal on input node from custom vi and ran the fpga vi. I got error saying contact ni.

Please find attached my custom vi and fpga vi. I would like to have digital signal on input node. Also I wonder if there's a digital waveform chart which charts the digital signal continuously.
