Is mixed-signal simulation a fantasy?

Comments(2)Filed under: Custom IC Design, mixed-signal simulators

The world is a mixed-signal one, or at least that's what were told.  The concept of "mixed-signal" simulation has been around since my days at Daisy (some 18 years ago).  And yet, the concept still struggles along. 

Some blame the lack of behavioral modeling expertise.  Others, that the concept of bringing together the hardest aspects of custom and standard cell design together in one fell swoop, is just too much for any one person to shoulder!  And yet for others, mixed-signal simulation is a standard practice employed with all their designs.

 So, what do you think?  Do you run mixed-signal simulators?  Do you avoid them like the plague?  Either way, why do you do what you do??

I remember my first look at the Mentor VHDL-AMS User's Guide, it was over 400 pages long! Talk about learning curve. I've seen at large companies that engineers specialize in either HDL or SPICE, but rarely combine the two. Trying to teach behavioral modeling to SPICE users is an uphill battle, maybe the next generation of college graduates will be more open to learning behavioral modeling.

Hi,
MY NAME IS VINAY,currently pursuing MTECH in MICRO-ELCTRONICS in a NIT.Now iam in 1st sem.I am very much interested to do my project in MIXED-SIGNAL design (ADC or pll or IO).How can i start going about this project? We got cadence tool.
I kindly request you to help me in this regard,looking forward for your response positively,
Thanking you,
Regards,
VINAY RAO
