I have a Simulink file with a single server. I want this single server to have an exponential distributed service time with a mean of 10^-3. How can I add this? In the block Single server, I think I have to do Service Time from: "Signal from port t". But how to make an exponential distributed signal with this mean?

If you took my advice from the previous answer, you can use the same Attribute function to apply an exponentially random number to the entity:

out_expRandNum = random('exp',10e-3);

You can then use the expRandNum attribute in the server by using the Service Time From Attribute option. Otherwise you can use 'From Signal Port t' and the event based random number setup for an exponential variation.
