Having recently attempted to get started with Simulation for debugging my FPGA code I found out that apparently the built-in LV support for native LV testbenches using simulated FPGA is supported only for ModelSim SE.
This is a shame since ISim is included with the FPGA toolkit.
If feasible, expanding the functionality to allos co-simulation with ISim would be a rather splendid idea ideed!
At present, if you are trying to simulate your FPGA's actual logic, using a custom VI like this:
Then you know that your custom VI test bench only has one case for methods (just a general method case, not a case for each method available). There are ways to get around this problem--for example, this example emulates a node and suggests using a different timeout value for wait on rising edge, wait on falling edge, etc, but one still has to write the code for the different methods.
My suggestion is as simple as this: make test benches easier to use by handling all of the methods and properties with a set behavior. That way, all one has to set up when creating a test bench is the input and output on each I/O read/write line. At the very least, it would be nice to have the ability to read what method is being called, so the appropriate code can be set up without complicated case structures.
This has been a huge frustration in my development. There is no way to debug a Flex RIO + NI1483 FPGA design other than to tweak, compile, and test with actual hardware. NI should provide a VHDL behavioral simuation of all of their modules so that full end-to-end simulation can be performed using advanced simulators such as ModelSim. This would facilitate a much more robust FPGA development cycle for their customers who have these types of tools available.
For the NI1483, a VHDL simulation combined with a VHDL Camera Link behavioral model would be even better. But the CameraLink model could be developed by the customers as it (At least) is a standard or can be gleened from camera manufacturer documentation.
