I wanted to carry out HW Cosim using System Generator 14.6. It does fulfill the 3 criteria given on page 199 of Xilinx
System Generator for DSP Version 9.1 user guide (sysgen_ug)
Since there is no in- built board support package for ZYBO in system generator (like ZC702) I tried creating one using SBDBuilder. However while creating New Compilation Target; I am unable to find Zynq as target-able device.
Does this mean HW Cosim is only possible using ZC702 & not with ZYBO Zynq Z-7010 at the moment?
Note:- Tried with Matlab R2013a as well as R2010a.

This is a known issue where 7 series devices are not shown for SBDBuilder.

Using 14.2, I could create board support file. Thanks for the guidance.
It creates JTAG Cosim model with all files except .bit file, so I used ISE 14.7 to generate .bit file (from CW project created in Simulink).
While running cosim following error was found
Could not find a ARM device on the board. Please check if the target is in:
1. Split JTAG mode - No operations are possible with ARM DAP
2. Non Jtag bootmode - Bootrom may need time to enable DAP. Please try again
Error occurred during "Simulation Initialization".
To resolve this I have already tried AR17966 and verified with MATLAB 2010a/2013a- ISE 14.6 and MATLAB 2013a -ISE 14.7 but both of them still gives the same error.
After this I downloaded the program through iMPACT and checked skip device configuration in JTAG-Cosim model. This somehow solved the above error but the scope output from hwcosim is 0, whereas the other scope output directly from simulink simulator (without cosim model) shows correct result.
Please help to get the correct scope results from hw-cosim. Thanks
