Hi all,

As a point of note, SPECCTRAQuest SI Expert includes SigNoise. SigNoise was
Cadence's original signal integrity tool and was sold as an add-on option
tool to Allegro. It is no longer sold separately, as the people who perform
SI analysis need to be able to view and perform basic edits to the database,
hence, SPECCTRAQuest SI Expert.

Carlos is entirely correct - SigNoise is comparable to the functionality
provided by XTK.

Todd.

  Hi Selvaraj,
           You need both specctraquest and signoise. Signoise is the
simulation engine for Specctraquest. whenever you run a simulation from
Specctraquest, SQ automatically runs signoise to perform the simulation.If
you want to use signoise without using Specctraquest, then you have to use
the command line mode(signoise doesn't have a separate GUI- you do
everything from the SQ/sigxp GUI). Generally this command line mode is used
for batch analysis. Normally, for the topology extraction and simulation,
you need both Specctraquest and signoise.
  With regards,
  Aloke

    Hello, Just I want to know these informations.. What is the difference
between the SpectaQuest and the Signoise from the cadence tool chain? Which
one will be used for signal integrity analysis? Which of these tools will be
similar to that of Viewlogic's XTK? thanks for any input. regards,Selva
