    analylis bus in SigXplorer Reply

    Hello!
    I want to analyse reflection for several signals or bus (for example, bus data, bus address).
    for single signal sigxplorer can perfom this analysis, but How does perfom analysis for several signals or bus in Sigxplorer?
    Docunent SigXplorer User Guide has description for Measurement Expression Editor. How can I open it editor? and in what program I can open it editor Alegro or SigXplorer?

    SigXplorer isn't the proper tool to be doing bus analysis. Allegro PCB SI (aka SPECCTRAQuest) has the ability to run batch simulations of multiple nets. If you are looking at just the reflection of these a bunch of nets, then the report mechanism from the Probe form would be your best tool. It isn't meant for what if analysis, but rather for simulations of routed (or unrouted if you desire) nets.

    If you want to do xtalk analysis of coupled lines in SigXP, then you would use the coupled line elements from the library. You can then sweep things like the trace spacing, dielectric constants, etc.
    The Custom Stimulus editor is built into SigXP. From the Measurements tab, you select Custom, then look at one of the default ones (like DieNoiseMarginHigh) to see the syntax. An app note can be found at:

    Hello John Horner!
    Thank you for your answer. I can't download HowTo_custom_measurements.zip. If don't difficult, Can you send it to me by mail: sergey-r@bercut.ru.
    I don't understand about which library for coupled line elements in xtalk analysis you speak.
    Kind Regards,
    Sergey

    Sergey,

    Please explain why you cannot download the file John recommends. It is a small zip file and should be downloadable.

    I have used Reget Deluxe 3.2 for download files. But Reget after several try write me, that cannot download it zip file and give next error: (No connection could be made because the target machine actively refused it.)

    Hello John

    I have read the "ss_custom_measurements.pdf" is it possible with allegro 14.2 suite?

    If so then how?

    Please let me know...

    Waiting fo reply.

    Check the header of SigXP when it is running. If it says SQ signal explorer expert, then yes all the techniques described in the app note will work. If it is not the expert level series tool, then they will not as that level does not have all the capabilities. There are upgrage paths available to get to the desired level of functionality.
