A new startup was launched this week that offers a new SPICE simulator that takes advantage of multi-CPU computers to speed analysis of transistor circuits. Cybereda is the name of the company and was founded by CK Lee, an EDA veteran who has many years experience with analog simulation at companies such as Nassda, Synopsys and EPIC.
The speedup claimed by this new SPICE offering is 10x over popular commercial simulators. I think they maybe comparing their runtimes to HSPICE. While faster SPICE simulations are always appreciated, Cybereda also claims that commercial SPICE offerings can easily product incorrect results even with simple circuits. I took a look at their web-site and they show an example of a MOS device driving a capacitive load. The commercial SPICE simulator gave the wrong answer. See http://www.cybereda.com/?page_id=12
My take-away from this is that you always need to check what your SPICE simulator is doing and understand what the impact step-size and tolerance settings have on the results.
Have you been fooled by a SPICE simulation? Let me know what happened to you.
Happy Holidays to Everyone!
