How can I improve the accuracy of sub-threshold simulations using MOSIS-provided SPICE parameters?
MOSIS lot-specific SPICE parameters will yield more accurate simulations with digital circuits than with analog. We do not currently optimize specifically the sub-threshold parameters in the MOSIS BSIM3v3 model cards, and we do not verify sub-threshold performance against measurements. These are certainly things we intend to implement, but resource limits prevent us from doing so at this time. MOSIS customers can obtain vendor-provided SPICE parameters when they are available. These are not lot-specific, but in some cases they are extensively binned and contain corner sets, and they may provide more accurate simulations for devices of given specific dimensions. support@mosis.com with your account number and other identifying information. –> To obtain these parameters, please see vendor-specific agreements, applications, and procedures for requesting access to proprietary vendor documents available through MOSIS.
