scale properties between technologies

adi84
Hi, I'm wondering if it's possible to scale a design's frequency, area or power from a technology to another. Let's say for example a design is implemented with a 65nm technology running at 500Mhz, area 3 mm2, power 10 mWh. It's there a way to calculate what frequency, area, an power would the design have if it were implemented using a 90nm technology ?

  • Hi adi84,

    This can certainly be done. However a number of things have to be kept in mind. Smaller geometries (<90nm) do not necessarily scale linearly on all parameters and some are pretty far from linear. Depending on your goals, such approach may or may not be accurate enough. I suggest you use something like the Incyte tool found at chipestimate.com. It provides a really easy way to do some early analysis of trade-offs across technologies and IP. We had pretty good results with it.

     

    hope this helps,

    gh-

     

  • Hi grasshopper, Thanks for the suggestion. I installed this tool and seems to be great. But what was I actually looking for is something like a formula to scale, the frequency, area and power from 65nm to 90 nm. I measured the energy consumption for an application running on a phone knowing what frequency and area the phone's processor has. I also know what technology was used for synthesis, 65 nm. What don't know is how can I scale the area, frequency and energy consumption value from the 65nm technology to a 90nm technology, I need to know what is the area, frequency and energy consumption of the phone's processor if a 90nm technology were used for synthesis. Regards, Adi
