I did a block diagram as follow, and no matter what sources I use (pulse generator, step, IC), the output signals are always on the order of 10^-5 or even smaller (10^-26)
following output shows the problem. I have tried to set the adder with double, but it didn't work
At the end, I want to notice that the same block diagram as above runs on other computer resulting in appropriate output as below, and i think there must be setting issues or ohter problem with my matlab

Hey Cheng,
I'm not able to reproduce the issue on my end. Could you share the following details for further investigation?
  • MATLAB version you're currently using
  • The complete SIMULINK model file
  • Brief description of what you're trying to accomplish
