Compact Modeling extension (Read 64 times)

A_Programmer Junior Member Offline Posts: 13	Compact Modeling extension Jun 19^th, 2006, 6:43pm I am using HSPICE Y-2006.03. Does it support the compact modeling extension? If not, is there any way I can output variables like gm, gd, and etc? Thanks a lot.

You could probably output the values with $strobe, of course, you'll want to be sure that ddx() works if you want gm.

Thanks a lot.

A colleague at my company noticed that the "analog functions" in Verilog-AMS were strange beasts -- you have to declare them inside the module, but they don't have access to any of the other module-scope items, such as parameters. So, I don't have a good suggestion for you. I know some people use macros instead of functions because they find V-AMS functions lacking.
