Title: Porting systems from one technology
Post by kamesh419 on Oct 13^th, 2006, 8:09am

Dear all,

I would like to know what all aspects one has to keep in mind when porting a system (in my case an SRAM which is in the layout level) from one technology to another (lower technology).

Thanks and Regards,
Kamesh.

These are generic thumb rules for any circuit and hold good for SRAM also
1. If the same devices available in the new technology, the aspect ratios are kept same. In the other words, shrink the geometry by the shrink factor. Change the mult factor of the devices if the new technology has limitations in max width.
2. For the devices which are there in old technology but the new technology's foundry doesn't have it, you need to look for closest device characterstics (through simulation) and compare the device strength with the desired aspect ratio. Extend it for resistances, metals etc.
