[PCB_FORUM] Re: Posy-Layout Simulation

William,

I've used both tools (and others) for pre and post layout simulation - summary 
of my thoughts below.

Hyperlynx:
- Interfaces to all major toolsets
- Easy to learn and use
- Great for quick analysis of individual nets, stackups, topologies
- Functions as a standalone tool
- Uses standard IBIS models
- Cost effective (best bang for the buck, although price has increased 
significantly since the tool was purchased by Mentor)


SpecctraQuest
- Interfaces only to Cadence tools (? may have changed in recent releases)
- Extrememly powerful .. can run batch analysis with ranges of parameters, etc.
- Fits directly into the Cadence "Expert" (or whatever they are calling it now) 
toolflow .. can pass constraints back and forth from analysis to design tools
- Requires model translation
- Very expensive

I'm not sure if SpecctraQuest is available in cheaper "scalable" modules as the 
other Cadence products are. Our implementation was a full blown "Expert" set of 
tools which was quite expensive.

My advice - Hyperlynx is a great tool for it's price tag. If you'll be 
performing many simulations of a large number of nets and can justify the cost 
SpecctraQuest is the best analysis tool I've used.

Hth,
Dave
