The one thing I am working on that I could use some assistance with is knowing the Digital Waveform file format. I can't find documentation on this format anywhere.
We are trying to get Serial Data Words to load into our NI-6561 in a reasonable amount of time. We are anticipating a thousand serial Data words at about 3K patterns each. Our existing method takes minutes to load, which is unacceptable. Using a "Read Waveforms from file.vi" (See Below) and feeding it all of the waveforms from one Digital waveform file (Could be a “DWDT Array Dlog” File) appears to be a promising solution. I have reverse engineered the format and have made it working model. It is a binary file. We need to know the real format of this file: what all the fields are, how long each one really is and if there are uses for what appear to be a null pad in the header. If I go with what I know we may find out down the line that we have problems based on our unknowns. Knowing the format can help us to be more secure when we build an outside tool to generate this file. So that our solution will actually work properly and that we can label each version of the file to assure conformance and maintainability.
