LabVIEW FPGA Simulation Mode - maximum amount of DRAM API

[Terry_ALE]

My application uses the function: LabVIEW 2015\instr.lib\niIFDig\Memory FIFO\v1\FPGA\DRAM\U512x1\Public\Create Resources.vi

The Host and FPGA code compiles and runs with no problem.

If I try to run it in simulation mode, Windows, that is the LabVIEW FPGA simulation software runs out of memory at this function.

The application needs 1048576 elements.

I worked around this by setting this value at 32768 using a conditional disable structure and I am able to run in simulation mode.

See screen shot below:

I figured this out 'by accident' and some NI people confirmed this is as being a known thing.  Could I get a link to a reference for future use and the training of customer/internal team members?

This is using LabVIEW 2015.  If it is better in newer versions that would be good to know.

Hi Terry_Ale:

      Is this VI part of a driver? I have been looking for it or for documentation on it but have had no luck so far.

Can you upload the code?

[Terry_ALE]

This is part of one of the following drivers:

LabVIEW FPGA 2015

NI FlexRIO 15.0
NI RF Device Drivers 2015.11

Thank you for the responses so far.  As it is, I am unable to post the source but I will extract the parts that are causing this to break and share.
