Manipulating a single Instance Iterations in Virtuoso

Battosai

 

I am trying to manipulate the parameters of a single instance of an array (I1<1024:1>). The instances contain a simple RC network and a current source modelling a rather complex circuit. All the instances are connected in series using a bus-notation. Now I need to add a unique delay to every single one of the current sources in order to simulate a propagating signal through this chain of instances.

My idea was to use a skill function to deduce the number of the instance and use it as a multiplier for a constant delay and add it as a parameter of the internal current source. This way all 1024 instances should have a unique delay that is a function of its instance number.

I am fairly new to Skill and seem to be stuck..I managed to access a single instance using ilInst~>name but this returns me the complete name i.e. I1<x>. That's about as far as I came..

Does anyone have experience with this kind of problem or any hints that might help?

    If you have an iterated instance, you can't set different properties on different members of that iterated instance. The whole point is that it's only a single component, but it's expanded to multiple instances when needed. So you can't do what you want - each would have to be drawn separately.

    ilInst is a special variable used for label display; you should not try to use it for anything else.
