I'm looking for simulation models that work with Mentor Graphics Quicksim simulator,
particularly for the at90s8515.

These would allow the designer to confirm the operation of the toaster controller with the
rest of his design.

We've looked at our usual sources and couldn't find anything. Any other leads would be
appreciated.

Thanks,

Hi John,

I'm affraid Atmel do not have Mentor Graphics Quicksim models for the AVR devices.

AT Present the only option available to you hear is to use a hardware model but this is VERY expensive.

A better solution would be to use Seamless from MGC this allows hardware/software coverification http://www.mentor.com/seamless. I don't know if the AVR devices will be suported, ask your MGC rep.

We have an old hardware modeller in house, so I did look at that solution.

The killer problem, besides the amount of time it would take to set up the model, is that the chip has an internal RC oscillator/counter that controls the reset timing. This would make it impossible to synchronize the real chip to the modeller. Oh well.

It makes me wonder how these types of controllers are tested in board-testers. They would hit the same sort of synchronization problems.

I will check out the 'seamless' product. Although, we have already asked Mentor and Synopsis for leads.

Thanks for the info.

Arild :

I was doing some further reading and found that the at90s8185 is available as a 'core macro' inside the ATL35 Gate Array series. When the designer wants to simulate the gate array, is the microcontroller a black hole? If not, could these models be made available?

We do have the Mentor VHDL tools available.

Cheers, John P.
