    ASCII vs. Neutral Formats for 3rd party apps?

    chris.smith

      In regards to ASCII output & 3rd party tools,

       

      ODB++ is not a perfect answer for other parties to interface or import results from an Expedition Project. What direction is Mentor moving

      to be able to compliment and/or partner with other toolsets?

       

      Is there a plan for any other or newer neutral format?

      For Engineering internally we need unencrypted ascii out for the CST PCB field solvers.  It doesn't accept  ODB++, so the only option for Expedition layouts is ASCII.  It is also necessary  to remove CES constraints, since CST will only read in net names from the old  net classes/props ascii file. The CST field solvers are 3D, allowing us to do  some additional analysis beyond what is possible in Hyperlynx.  We've also found  it is beneficial to compare the output from multiple field solver types to help  verify the accuracy of our models.
