| PS Constant | Generate constant physical signal |
| PS Counter | Increment output signal by 1 with every time step |
| PS Random Number | Generate normally distributed random numbers for physical modeling |
| PS Repeating Sequence | Output periodic piecewise linear signal |
| PS Uniform Random Number | Generate uniformly distributed random numbers for physical modeling |
Physical Signal Unit Propagation
Physical signal blocks propagate units.
Upgrading Models with Legacy Physical Signal Blocks
Prior to R2019a, physical signal blocks did not propagate units.
