Modifying variables during simulation

hi,

Is there a way modifying the value of a variable as a simulation runs, like  in AMS simulations?

Imagine that I am running a transient simulation  to find a trimming code and, without running another simulation and using calcVal, I want that the second part  of the simulation to use that trimming code that has been found.

Is this possible using spectre? This is AMS style of doing things but I cannot find a way to do this with Assembler.

Thanks in advance.

Best regards,

Pedro
