A error occured when selecting "Hybrid CE DCM" for "Multirate Implementation"

Jump to solution

Hello frends I am confuse about DCM working in system generator.

If I select "Hybrid CE DCM" for my "Multirate Implementation",then a error will be reported as follows when generating netlist.

--------------------------------- Version Log ----------------------------------
Version                                 Path
System Generator 11.4.2254              D:/install/Xilinx/11.1/DSP_Tools/nt/sysgen
AccelDSP 11.4.2254                      D:/install/Xilinx/11.1/DSP_Tools/nt/AccelDSP
Matlab 7.9.0.529 (R2009b)               D:/install/MATLAB/R2009b
ISE 11.4.i                              D:/install/Xilinx/11.1/ISE
--------------------------------------------------------------------------------
Summary of Errors:
Error 0001: caught standard exception
     Block: Unspecified
--------------------------------------------------------------------------------

Error 0001:

Reported by:
  Unspecified

Details:
standard exception: XNetlistEngine:
An exception was raised:
java.lang.NullPointerException

--------------------------------------------------------------------------------

If I select "Clock enables" for my "Multirate Implementation",then no error will be reported when generating netlist.

Can anyone tell me what does mean this error and how to fix it please ?

Thanks a lot.

Looks like the Hybrd CE DCM is not supported for Multirate Implemenations.  It should give an error like this though.  You should probably open a Webcase.
