Top level ADC testbench

tobiasedstrom

Hi,

I am running simulations on an ADC. I use ADE-L to generate the netlist and the testbench itself is written in skill . 

I have until now used Spectre as simulator and it have worked flawless. I found some AMS configurations however, that could be used to improve simulation speed (which is a major concern). So i decided to change simulator from Spectre to AMS.

The process is that I generate a VAMS netlist from ADE, then the skill testbench picks it up, setting all necessary variables and starts the simulation. When changing simulator, the simulation does not even start so i assume there are some errors in the configuration.

The following errors is shown in the log.

*Error* putprop: first arg must be either symbol, list, defstruct or user type – nil

and some of the following errors, for different variables

I dont really know were to start debugging, so i would appreciate any hints or ideas :)

Thanks,
Tobias

  • That's a rather non-specific error - generally suggests that some low level code is dealing with data it wasn't expecting, and didn't catch it properly. I also don't know what you mean by a SKILL test bench in this case.

    I suggest you contact customer support - it's really going to be hard giving advice without seeing the details, without them just being wild stabs in the dark!

    Regards,

    Andrew.
