I ran a simulation for a combinational logic circuit with 8 inputs, 4 outputs inside MODELSIM. When I view the simulated waveform everything looks fine, however when I export result to a list file there are some intermediate valued related to deltas inside a time slot like this:

```
t(ns) delta               output input
    460  +1                   4'h1 8'h2E 
    460  +4                   4'h0 8'h2E 
    460  +5                   4'h2 8'h2E 
    470  +1                   4'h2 8'h2F 
    470  +4                   4'h3 8'h2F 
    480  +1                   4'h3 8'h30 
    480  +4                   4'h2 8'h30 
    480  +5                   4'h4 8'h30 
    480  +6                   4'h6 8'h30 
    490  +1                   4'h6 8'h31 
    500  +1                   4'h6 8'h32 
    500  +4                   4'h7 8'h32 
    500  +5                   4'h5 8'h32 
    510  +1                   4'h5 8'h33 
    510  +6                   4'h7 8'h33 
    510  +9                   4'h5 8'h33 

```

I want to know what are these intermediate values and will they cause problem for my circuit or not?   
 e.g. there are 3 value for t=460ns
