SpecctraQuest is GOOD/BAD Tool for Board Level Simulation < 400 MT/s??? Gurus, =20 I recently heard a fellow say that SpecctraQuest is not an acceptable tool for SI simulation (timing, signal quality) due to imperfections and/or bugs in the program. Basically, the assertion was that the tool would not generate correct results. I would like some opinions from industry experts as to the viability of the tool. =20 The application I am interested in is board level simulation of digital busses using IBIS models. I plan to use the tool primarily to investigate solution space via flight time analysis. Signal quality issues (ringback, non-monotonicities) would limit my solution space as well. Can this tool be used for such a purpose, or does the SI community generally expect faulty results from this tool? BTW, switching frequencies for most busses I would be working on is less than 400 MT/s. =20 Are other SI experts in the industry using SpecctraQuest to simulate such busses? Are other folks in the industry yielding accurate results using this tool, or should I discount the use of this tool as a bad choice based on collective industry experience? =20 Please respond... the more responses I get, the more confidence I have in tool selection. I will post the results of poll as favorable # vs. unfavorable # of responses should the forum be interested. =20 Thanks, -A Concerned SI Guy =20 =20 =20 =20 =09 --------------------------------- Yahoo!
