LabVIEW FPGA Cycle-accurate simulation with the I/O adapter module NI-6585

[kakajee]

Hi,

board: FlexRIO NI 7962-R with NI-6585 I/O adapter module
SW: LabVIEW 2010 SP1, ModelSIM SE 6.6C

I am trying to simulate a LabVIEW FPGA project including the I/O adapter module NI-6585 with Modelsim.
Basically, I'd like to furnish simulation stimulus signals thru the I/O adapter module (NI-6585) to
VHDL CLIP modules.  
The simulation export process doesn't complete correctly for the reason of a missing simulation
model for the corresponding I/O adapter module, NI-6585.

Questions:

1. Is it possible to use an I/O adapter module in cycle-accurate simulation with Modelsim?

2. Is there an example/tutorial of LabVIEW FPGA project for the cycle-accurate simulation with an I/O adapter module?

Thanks in advance.

Hi,

And thank you for posting here.

Please install first the right version of ModelSim for you 2010 SP1 LabVIEW because it seems that the 6.6 only fit for the 2011 version of LabVIEW.

Tell me if it changes something for you.

Hello!

To answer your questions:

1. Is it possible to use an I/O adapter module in cycle-accurate simulation with Modelsim?

Yes

2. Is there an example/tutorial of LabVIEW FPGA project for the cycle-accurate simulation with an I/O adapter module?

Yes, however, the tutorial is not yet ready to publish at this moment as it is still being worked on. We will work on getting a preliminary copy of the tutorial to you as soon as we can, which may be 1-2 weeks. 

Let me know if you have any additional questions.

Hello,

Thank you for your answers. I'm looking forward to getting the tutorial.

Hi Ben,

I am looking for a simulation model for the NI-5734 IO adapter module. Any idea on timescales when this will be available? 

Ian.

Ian,

Hello! We don't currently provide the simulation models for any of our adapter modules and currently do not have any plans to provide them at this time. The tutorial that I had previously mentioned simply shows how to create a simulation model from the 6581 CLIP, this is possible due to the simple nature of that particular CLIP. Some of the FlexRIO Adapter Modules with ADCs, DACs, and other more invovled componets, such as the 5734, have much more complex Socketed CLIPs that would require much more work to generate a model for than this tutorial will cover.

If your goal is to simulate your code that contains FPGA I/O nodes from the Adapter Module. My suggestion would be for you to create a simulation version of your FPGA code that has all the FPGA I/O Nodes that are not actual AI/AO/DIO stripped from it. You can then replace the FPGA I/O nodes that are the AI/AO/DIO with a DMA FIFO or LabVIEW Memory item. In this way, you can test your code's logic with an expected signal.

I hope this information helps!

kakajee,

The tutorial is now online. It is specifically for the 6581, but should outline the process in a way that (with some work) you can simulate the 6584.
