Title: VHDL-AMS VBIC model? Post by the_pd on Sep 16th, 2011, 4:09pm I am in need of a VHDL-AMS VBIC implementation. So far, it looks like Verilog-A is the language of choice, however. Anyone know where I could find a VBIC model in VHDL-AMS? Thanks! |
Title: Re: VHDL-AMS VBIC model? Post by loose-electron on Sep 18th, 2011, 1:45pm Strange mix of platfoms. Verilog A or AMS is generally used for functional level models, not transistor level models. If you need to simulate at the transistor level, perhaps you should consider using a EDA platform with a Spice-Spectre type of simulator? |

Jerry - You've missed the revolution in transistor-level compact modeling: almost all the latest transistor models (PSP, BSIMSOI, VBIC, Mextram, Hicum, ... and soon BSIM6) are written/developed in Verilog-A. Spectre, HSpice, Eldo, etc. all have Verilog-A compilers. The users can then modify the source code to add new equations / model features. That said, it is Verilog-A; I can't recall ever seeing a compact model written in VHDL-AMS, other than maybe a basic diode as an example. Verilog-AMS added a bunch of features to the language in LRM 2.2 to make compact modeling easier, and that's where the developers have gone. |
