How to store a value/Store function in Verilog-A/AMS

Hasan91

Hello guys,

I have been looking for a storage element or something like that (in Verilog-AMS/A) so that I can keep the output value of my circuit forever, after one-time simulation. 

I think it is very similar to a ROM or OTP. So I was wondering if anyone has implemented a ROM/OTP in Verilog-A/AMS and I would appreciate it if you could share it with me.

I couldn't find a proper function for saving a value in Verilog-AMS/A. The output value will be lost after rerunning or say turning the power supply off. 

Thank you in advance.

    What do you mean by "forever"? You mean for the rest of the simulation? Or for every simulation you run after that? It's an odd request if the latter; if the former that's just a variable in VerilogAMS so I assume it can't be anything that straightforward (look at any model for a flip flop or register in Verilog).

    Thank you very much, Andrew.
    Let me put it this way, maybe I can explain better. I have two different blocks/circuits, let's call them X and Y. I want to save the output of X in a file so then later I can use it when I simulate circuit Y.
    X and Y are separate circuits and I cannot simulate them simultaneously.  I only simulate X one time but I simulate Y several times (different corners). Basically, X provides an initial condition for Y and I want to use the same condition for all simulations.

    I am looking for a function or something in Verilog-a that can store the output(s) in a logfile.
