Is the emulator on the LM4F232HFQD EKS one of the XDS Reference design?

I am prototyping code for a target system on an EKS LM4F232H5QD.  Our target hardware is still a couple of months out.  We need to choose an emulator.  The EKS emulation is workable, but has periods where I beleive the emulator fails - interrupts stop working but start working again after power cycling the EKS and closing-opening CCS, etc.  (I sometimes think that using the virtual terminal on the EKS can prompt the emulator to fail.)

I get much work done with the EKS system.  If the emulator is the XDS100 reference design, I would gamble the money to go to an XDS 5xx reference design emulator - hoping to avoid the issues I have seen on the EKS.

What is the difference between the EKS emulator and one of these reference designs?

    They are not the same.  The XDS100 and other XDS are different from the onboard debugger.  I have used the XDS100v2(ARM) with this board and it seems to work fine.

    Does the V3 emulator buy me much?  I am unfamiliar with IEEE 1149.7.

    Are you using the TMDSEMU100V2U-ARM from BlackHawk?  We are debating with the HW dev guys here on 10 vs. 14 vs. 20 pin connectors.  I certainly understand that they want the smallest connector as our target does not have all the real-estate in the world for a 20 pin connector.

    If not, what did you do to go from the 14/20 pin connector to the small 2x5 on the EKS?

    There is a web page here that has a lot of information about XDS100:

    http://processors.wiki.ti.com/index.php/Xds100

    The one I am familiar with is the XDS100v2 for ARM (from blackhawk) which means it has the ARM 20 and 10-pin connectors (both).  You can plug it directly via ribbon cable to the small connector on the eval board.

    You can buy one from TI from this page:

    That page suggests that it is not yet available from distributors.
