Title: Using components from Technology Library in verilog A module
Post by king28 on Apr 6^th, 2015, 8:21am

Hello everyone,

I want to instantiate a NMOS transistor from my technology library inside a verilog AMS module. This is needed because I am trying to modify the characteristics of transistor externally using some other devices for which model does not exist. So I write IV characteristics in a file and use that in verilog A. Now I need to instantiate a NMOS transistor as well inside the verilog A module. How can I do that?

Thanks

The Verilog-AMS Language Reference Manual, Annex E Spice Compatibility, discusses instantiating Spice elements in a Verilog-AMS module. Beyond that, you'd have to check with your simulator vendor to see if there is any special setting necessary for this to work -- how does the simulator resolve instances inside modules? I've seen resistors inside modules, but I can't say I've ever seen an NMOS instantiated this way.
