Using extracted view with iterated instance

Hello,

I am working on a design of SRAM and I am trying to validate it with an array composed of 4 words of 8 bits.

I designed a bit  cell which has been instanciated 8 times in another cellview to create a word:

and then I use an iterated instance of my word cellview in my test bench:

I'm using the AMS simulator with ADE explorer to validate my design and everything works as expected when I use the schematic view. All the words are initialised when the word lines are high.

However, when I use an extracted view (defined with the config view of my cellview testbench) of my layout, it seems that the stored values of 2 different instances are connected.

(here is and exemple with the bits 6 and 0 from instance 1 and 0 that are suposed to be initialized differently)

Here is a screenshot from my view config:

When I do this simulation using 4 different instances of my word cell , I have the same behavior than in schematic based simulation (with expected variation due to the parasitics):

(here Q1<0> and Q1<6> are initialized after ~20ns and I do not use any initial conditions, this explain the behavior just before 20ns)

I admit that I am stuck with this problem, do you have any idea on the reason of this behavior

Thanks in advance

Mathieu
