Hi all,I've been asked by management to justify the large cost for SPECCTRA maintenence.One question ive not been able to answer is are there any new significant features to SPECCTRA since about 2000?At the moment, the only new item i know of are 'layer sets', which is a nice addition, but is not what i would call significant.Ideas peoples?roberth.
Robert, I have enclosed the Features which have been implemented into Specctra from 15.0 thru 15.7. Beyond enhancements to the software maintenance also allows for software updates which contain fixes to P0, P1 and P2 pcrs, just a side note.PSD 15.0
Turbo Stagger option A turbo stagger switch has been added to the options section of the Router setup tab. This is used to improve routing performance though staggered pin connector fields. If left unset, router has tendency to route around the connector thus increasing lengths of routed traces. Not recommended for global routing due to performance degradation.
Multiple Matched GroupsGuidelines for source synchronous buses require their nets/pin pairs to reside in multiple matched groups. Prior to 15.2, Allegro restricted a pin pair to only one matched group. 15.2 removes this restriction as nets/pin pairs can reside in more than one matched group. Interactive routing feedback displays worst case margins when processing more than one condition.
