LabVIEW FPGA and VHDL/Verilog code

[Oli_Wachno]

Hi subdew,

about a year ago (long enough to not remeber too well   ) I used the VHDL node with LabVIEW FPGA 1.1. I remember, that I had some startup difficulties with external files. If I remember that right, it was an issue of absolute and relative paths.

I had some problems with the generics as well, but I think if have to meditate a little while to remember how I have solved that. 

An issue that used to be quite annoying with this old version was the fact, that the VHDL node was limited to 28 terminals or so. Afaik, LabVIEW versions 8 have solved this.

I don't know if this really helps, but I'll post as soon as I've checked!

Regards

Oliver

kindly, tell me where can i find the HDL Interface Node ? is it available on labview student version 8.5 ?? I want to see the ouputs of my vhdl ports on labview so that i can do functional checking of the code/test bench.

I have both the test bench and code in vhdl and the code is all about the circuit which has simple logic gates connected to each other.  

I want to check the output ( logically using numerical indicator or graph ).... let me know if its possible.

Hi Miaa,

in order to work with the HDL node, you must have the FPGA module installed. I don't know, if it comes along with the student version. If it does, check the FPGA palettes; unfortunately I haven't worked with the 8.5 FPGA module yet.

Hi Miaa,

The student addition of LabVIEW unfortunately does not have the FPGA module included; however, many universities have licenses available for students to use. Please let me know what university you are attending and I can point you to your university contact for National Instruments software.

Once you receive the FPGA module the HDL Interface Node is located in the Functions Palette (block diagram) >> Programming >> Advanced. However, in order to use/locate this function you must create an FPGA project and then create a VI under the FPGA target (in the Project Explorer right click on your FPGA target and select New >> VI) because the HDL Interface Node is not available for use on a normal VI hosted on your PC. 

In the meantime, here are a few links that will introduce you to the HDL Interface Node and its capabilities:

I hope this helps to point you in the right direction for your development and I look forward to your response. Have a great day!
