Simulating a circuit in an array

delgsy

Hello,
I want to simulate a circuit containing 10 cells arranged in a 1 dimensional array.
Only 1 out of this 10 cells is turned on at a time.
So, the other 9 cells are either turned off or modeled with parasitic RC from the metal lines.


In my mind, I would like to realize something like in the picture below.
The signal that I am interested in is measured at the right side.
Is there a way to realize this?


I tried making an array expression with a variable size, like I<1:n>, it does not work.

    Is it possible to add an enable to each of your 10 instances? This will provide a 10 bit bus that you can set with a variable to enable one of the 10 cells in a simulation set.

    Yes, that is possible and I have thought about that.
    But, the output line is shared with all the 10 cells.
    Is there any mechanical switch in the library that completely open when not selected?

    You could use the switch component in analogLib - this is actually a relay (see "spectre -h relay").
