What is NeoCircuit?

Hi Daniel

Neocircuit is an auto analog/RF circuit design tool. With appropriate design objectives (e.g. phaseMargin=70deg, offset<1mV, etc) and testbenches, it can produce an optimized circuit that meets all (or nearly all) targets. You can read more about it here. It has already been integrated into ade-XL in IC61 but is still available for download at our downloads website. : )

Thanks for this answer! I have one another question. Where I can get the User Guide of Cadence ic 6.xx? I need the User Guide of the new ADE XL because there are explications about NeoCircuit I think. The old User Guide (version 5.xx) don't have any information about NeoCircuit. Please help me!

Install IC613/IC614 and then start the documentation? (e.g. typing "cdnshelp" or using the Help menus inside Virtuoso).

That said, the IC613/IC614 documentation will not cover anything about NeoCircuit - since the tool is ADE XL/GXL. It has similar concepts to NeoCircuit.

If you want to find out more about NeoCircuit, install NEOCKT34. 

Or look at the documentation on support.cadence.com .

You have said that ADE XL has similar concepts to NeoCircuit. How I can use this similar function in the ADE? Does it work in the same way like NeoCircuit? Did Cadence chang the methode of this program as they integrated it in the ADE?

Hi Daniel

The functions have been incorporated into ADE-XL/GXL but the look and feel would certainly be different. Perhaps it would be best to simply try out ade-XL/GXL using IC614. The user guide is located at:

/your-path-to-IC614/doc/adexl/adexl.pdf
/your-path-to-IC614/doc/adeGXL/adeGXL.pdf

Thanks for the answers. I will see where/how I can use this function!

And for a high level summary, you could look at the ADE Family Datasheet.

One another question: Does this function run automatically or do I have to set it manually? If I have to set it manually where I can do this?

Peach,

Not really sure what that question means. 

Once you've set the goals for the optimisation, and the things it is allowed to vary (which you need to set up manually), you hit the run button and then it will automatically search for a result that meets the criteria you've specified.

I really suggest reading the datasheet (at least) and documentation (better) to get a fuller understanding of what the ADE XL/GXL tools do (GXL is the tier where optimisation comes in; XL is the multi-test specification driven environment). It's all built on top of the standard ADE (now called ADE L) that you're probably familiar with. The difference is that you can have multiple testbenches set up with ADE XL and GXL - so it's like optimizing over multiple testbenches at once, with corners and monte-carlo both being available too.

Best Regards,

Andrew.
