how to flip the inputs of an simulink block

Hi everyone
I have an integrator block, and I want to invert its inputs, so I explain
the first input is x the signal to be integrated (the top input)
the second input is y the initial condition (the bottom input)
I want that x became the bottom input and y the top input
thanks in advance

See the image below. A variable switches the input on the switch blocks - see switch for information on setting the input conditions. In this figure the input is switched by a constant but you could replace that to suit your needs (a signal generator for example).
So in this example whilst the switch variable is not greater than 0, input 1 is A, and 2 is B. When it is, these swap, A becoming the input to 2, and B becoming the input to 1.

XAXRXTX,
Would my solution for switching the inputs not work for your scenario then?

You don’t need to switch the inputs. Just negate the result. It has the same effect.
