I'm working on a circuit which requires long transient simulations for a part of the circuit to settle, and I am therefore trying to utilize the State File options of spectre.
I save the state at a point in my simulation when the load has settled, and start simulations from that point.
I know I cannot change the circuit and use my state file, but I can change the parameters of devices, which is what I want to do.
This works fine in ADE L along with parametric sweep.
But, when I try to sweep global variables in ADE XL, the variables does not change in the simulation. If I change parameters the devices do change in simulation.
My problem is that I have a veriloga block, and it does not seem to be possible to pass a parameter from the veriloga block to the parameters in ADE XL.
I can define the parameter of the veriloga block to be equal to the value of a global variable, but since the global variable has no effect when using a state file, that approach is not usable.
I have not been able to figure it out from the documentation how to pass the veriloga parameter to ADE XL parameters.
Does anyone know how to do this?
Or how to make variables in ADE XL work when using a state file?
