Design based on Nangate 15nm OCL in cadence virtuoso environment

Carmichaeli

Hi everyone,

I plan to design a circuit under 15nm process technology, so I downloaded 15nm Nangate Open Cell Library (nangate.com) and corresponding PTM cards (ptm.asu.edu). But the 15nm Nangate OCL (2014_06.A) don't have virtuoso schematic cell (in 45nm process design package, Nangate OCL provides schematic cell library "NangateOpenCellLibrary" that can be imported into cadence directly). 
Could anybody tell me how I can use the 15nm OCL file and model cards to make a design in virtuoso environment as I did in 45nm process technology?

Thanks a lot!

Regards,
Wayne

    You are using too old a version of MMSIM. In the initial versions of MMSIM101, level 72 was not recognized. In hotfixes of MMSIM101 sometime after MMSIM10.1.1 (and certainly in all versions of MMSIM111 and later), level 72 is mapped to the bsimcmg model (or possibly bsimmg dependent upon the parameters - I'm not sure as I don't have a working example). Since we've had MMSIM111, MMSIM121, MMSIM131 and MMSIM141 since then, you would be advised to use a newer version of the simulator (particularly since technology is moving fast, and a 15nm technology is pretty modern).

    Regards,

    Andrew.
