[SI-LIST] Re: tools for really high speed

Lynne,

CST Microwave Studio and Ansoft HFSS can both handle the 3D full wave 
simulations at these frequencies.   To create spice-type models you will 
need to convert s-parameters derived from these tools into passive 
time-domain simulation models.  There are several commercial tools on 
the market that perform this function.  I have validated Sigrity 
Broadband Spice with CST Microwave Studio to 40 GHz. and 50 Gbps 
signalling against measurement, with the end simulations being done in 
HSpice.
