Test vectors for floating point unit

I have designed a 32-bit single precision floating point multiplier and also a separate add/subtract unit in Verilog. I have a script in MATLAB that I wrote that generates a bunch of random floating point numbers and generates a test bench in Verilog. I compared the results from the ncverilog simulation to those from MATLAB and verified that my multiplier works correctly and that my add/subtracter works correctly as well. However, I want to know a list of test cases that stress test my floating point unit. Is there such a list? I know of some programs like Softfloat, but that tests a floating point of a computer, rather than being able to merge that with a verilog test bench. I should also mention my unit doesn't support exceptions like overflow, underflow, and doesn't support denormalized values. The rounding mode is round to nearest. Thank you!
