Hi Claudio, No, it is not possible to define a C/C++ function in an element. Is the math function something that cannot be described as an equation or a table of time and voltage points? Common Model Interface (CMI) allows you to use a dynamically-linked shared library, to integrate MOS, JFET and MESFET models into HSPICE.

I'm working with HSPICE from Avant!, version 99.2. I have a question about drawing up netlist file: is it possible to write in the instruction statement any functions in Borland C/C++ language? Example: Behavorial voltage source between node 1 and 0 E1 1 0 VOL= ' voltage(A0,A1,A2,....) ' where ' voltage(.....) ' is a C/C++ function allocated in a source file. I've learned any documents about CMI (Common Model Interface) as option of Star-Hspice on www.synopsys.com: is CMI useful at my necessity? Or there is another way to do it? Thanks for all. Regards.
