    EBD Model in Design Link Reply

    I have a setup consisting of my board and DML models converted from EBD models. The system is linked together by designlink.
    I always get different results (waveforms), when I simulate using SpectraQuest (Allegro PCB SI) or using SigXP. I assume one or both of them can not handle the EBD models correctly. What is your recommended way to do the simulation?

    Since extracting to SigXp would give wrong interconnects for the designlink using boardmodel, simulating in SQ is highly recommended. It would give you more acurrate results.

    Hi lwang,

    Thank you very much for your reply! Do you know how to setup a custom stimuli in SQ, so that we can use random bits sequence.

    Best regards,

    So far, as I aware, there is no direct way to do so. The only way to do so go thru Constaint Manager. You can set up an ECSet with Custom Stimulus in it and apply it into the net (XNet) you need it.

    If you want to run sims in SigXp you need to convert the board model into espice black boxes using the command board2sigxp.pl. This script will convert the board dml file into espice black boxes that can be loaded into your library in SigXp and then be used to replace the extracted conductor models from the board dml file. You will need to know the net name used in the board dml file as that name will be part of the conductor model in SigXp. It helps to have a schematic of the board model so the circuit can be accurately rebuilt.

    You should be able to specify custom stimulus in Allegro PCB SI v15.7.
