si tool
Which is the widely used SI tool or extractor for package analysis.
APD SI 620 from Cadence
SpeedXP Suite from Sigrity
Q3D/TPA from AnSoft
PakSi-E from Optimal Corporation
Please let me know whether there any other tools which does the same.
Thanks in advance.

I want to know that how much can Ansoft HFSS do in Package SI analysis.
I think each tool has its strengths and weaknesses. I have experience with Sigrity tools. Speed2000 is the time-domain tool which can be used in both SI and PI analyses. Pretty unique in many aspects. It can do the whole PCB+PKG sims with consideration of all couplings btw signals and power/gnd.
Package SI Analysis
There are lot of expectations from Package SI analysis engineers,
hence there is no one tool addresses all the issues such as
1. Simulation engines required
Both Time-domain(Spice Based) Simulator and Frequency Domain (Harmonic Balance) Simulator
2.Integration of EM Simulators or RCLK Extraction Engine
3. Support of Data formats DXF/IBIS/GDSII, etc
4. Should cover wide application from Digital /Analog/RF/Microwave range...
Hence acombination of RF/Microwave Circuit tools + any of the above mentioned should be OK...Ex:
AWR SI Design Suite (http://www.appwave.com/products/si/ )+ SpeedXP Suite from Sigrity or PakSi-E from Optimal Corporation is the best suggested tool flow for Package SI analysis...

For low freq (1GHz) we are using Q3D to extract the model and proceed to Hspice for SI analysis
For higher freq, HFSS is used to model the package and same Hspice for SI Analysis.
Latest trend/development in Ansoft Designer makes it a good alternative for full path simulation i.e. when combining package and MB in one simulation
PowerSI/Speed2K is mostly used in power integrity analysis in here.
