The method for setting ic in multiple instances has already been explained by Andrew under the following link and is working fine:
However, when I do the same while using AMS, it is not working. In fact, I want to simulate an SRAM array with some functional blocks that's why I have to run it on AMS in config view. But the problem is that the ic file (abc.scs) after being set in simulation files is not going to affect the nodes which I intend to set to an initial condition (e.g. either 0 or 0.9V), nor I can see it in the generated netlist.
