If you want to do it directly, you'd have to write a VPI (Verilog Programming Interface) function to do it - i.e. write some C/C++ code and then pass the information to the simulator.  I'd be surprised if any mainstream simulators have this as a built-in function.

Alternatively you could use the $readmemh function, but you'll have to convert the data to something suitable.

Or you could do a co-simulation between AMS Designer (Cadence's AMS simulator) and Simulink, say.
