To solve this problem, NI has several products that you could probably use.
If you have access to the LabVIEW Control Design and Simulation Module, look at the shipping examples:
C:\Program Files (x86)\National Instruments\LabVIEW 2015\examples\Control and Simulation\Case Studies\Electrical Machines\DC Motor
C:\Program Files (x86)\National Instruments\LabVIEW 2015\examples\Control and Simulation\Case Studies\Mechatronics\DC Motor
Those examples don't simulate the H-Bridge, but can easily give you an idea of how to simulate the dynamics.
However, this example where a 3-Phase H-bridge is used for brushless DC motor, but it can be adapted to this:
C:\Program Files (x86)\National Instruments\LabVIEW 2015\examples\Control and Simulation\Case Studies\Electrical Machines\Brushless DC Motor Drive\Brushless DC Motor Six-step Control.vi
Although we don't simulate DC motor directly, I think you could easily create a DC motor from the brushless.
Then, if you really want a comprehensive simulation of H-bridge with connection to FPGA, then you must look at this community:

This will give you a lot of ways to do simulation with power electronics.
Hope this helps,
