    Allegro Constraint Manager (CM) Vs Specctraquest reports Delay Reply
    We are wondering why we are seeing some differences in Allegro 16.3 CM reports and post layout extracted specctraquest reports for diff pairs signals (specifically electrical length and physical length) for prop delay in relative prop delay for the matched length group. We have set up all board parameters (X-section) and also included z-axis correctly and also we believe that we have set up the correct ibis models, preferences etc  in specctraquest for simulation.Thanks in advance, - Hitesh.
