Hello, =0D This is regarding the SI issues on the board. =0D I hope I can get some clarification from u on the doubts listed down, =0D - Does propagation delay change on a bidi bus if I simulate in both directions( from A to B and B to A points) (in case if I simulate both in fast or typ or slow mode)? =0D - Does propagation delay depend on the driver selection, ie. fast,slow,typ? If then should I get different pd for each time I simulate a signal with fast/slow/typ drivers? =0D - This one is also regarding the pd. If I change the R,L,C parameters of connector (in a multiboard SI simulation), will the propagation delay change? Is there any way where I can change R,L,C parameter of transmission line separately in Specctraquest(I see only the option to change impedance!!) ? =0D Regards Santhosh =0D Confidentiality Notice=0D The information contained in this electronic message and any attachments to= this message are intended for the exclusive use of the addressee(s) and may contain confidential or= privileged information.
