Error when doing Monte Carlo Simulation

OrangeHalo

Hi all,

I am doing Monte Carlo simulation with IC617 and TSMC 180nm PDK. I am using ADE explorer to do the simulation. But the simulation failed with the following error:

ERROR (EXPOLRER-5052): Monte Carlo run stopped because no statistical data generated for the test.

I ran different corners and it turned out that those simulations are running smoothly. But I am not sure about how to set model sections in MC simulation.

Here is how I set the MC model sections:

Basically I use typical mosfet, bipolar transistor and resistor to build a bandgap reference circuit. And I do set the the models to be those with mismatch characteristics. I think the model sections in the screenshot are enough to do the simulation.

Here is how I set the MC simulation:

Here is how I set the output signal:

Could someone please help me with it or give me some hint? 

Thanks in advance.

Best,

Orangehalo

    This is probably best handled via customer support, as it needs us to have access to the same PDK you're using. The key thing is that  you need to ensure that the "statistics" blocks have been read - I'm not familiar with the latest incarnation of that process to know which sections you need to include for this to work (also, there are several process variants with technology libraries with similar names).

    Of course, somebody may recognise the problem fo this particular setup, so you might get lucky here - but customer support is the safer bet, in my opinion when a specific technology is required.
