Incisive vs Spectre XPS

zaratustra

Hi,

I have a question that may be out of scope of the forum but I couldn't find an answer nowhere else. The question is:

Is there any difference between Incisive and Spectre XPS in terms of performance, memory usage etc. for gate-level simulation?

Thank you,

Raphael

    This is comparing apples and oranges. Incisive is an event driven simulator which simulates gate level designs as logic; Spectre XPS is a FastSPICE simulator which simulates gate level designs at transistor level and can accelerate the transistors using FastSPICE techniques (for digital portions). Incisive (now Xcelium) will be considerably faster than any FastSPICE approach.

    I thought so, but I had to ask to be sure.

    Thank you Andrew.
