LabVIEW code development without hardware

We have a test fixture we've designed.  It will contain a frequency counter, DMM, Arbitrary Waveform Generator, Spectrum Analyzer, etc all within a VME chassis.  We're using TestStand as the test executive, but our tests are primarily going to be written in LabVIEW8.  We're just now ordering the test equipment and PCI, VXI cards, and other hardware.  The lead times on some of this hw is 20 weeks.  What's the best way to write code for our tests that use these cards when we don't actually have the hardware?  Assuming some of the test equipment is IVI compliant, how, in LabVIEW, would I begin creation of some common method calls (i.e. getFrequency, setFrequency) for these devices?  If the hw were here, I could configure MAX to recognize those devices, but we don't have the HW.  Does anyone have a suggestion for where to begin.

Part of the IVI specification is a simulation mode. You can install the IVI drivers and in MAX set them to that mode. Simulating other hardware will depend on the hardware and the drivers you use. for example, if you are using an NI DAQ board and DAQmx, you can enable simulation mode in DAQmx.
