problem with system generator 11.3 ---please help me

Jump to solution

hello,

 

   I installed ISE 11 (System Edition) yesterday ,and then updated to 11.3.  But  when I use SystemGenerator 11.3 with matlab 2009a,  run a simple example design about  "Demonstration on Using the Clock Generator (DCM) Option " (this design is an example ,or we can say ,it is correct ),   It occured a problem about:  

 

standard exception: XNetlistEngine: An exception was raised: com.xilinx.sysgen.netlist.NetlistInternal: ERROR:coreutil - Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine.. More information can be found in C:/Temp/sysgentmp-Administrator/coregen_work/cd7b1b49456204d489977bfaad512703a/coregen_tmp/coregen.log at E:\dcm_case1\hdl_netlist\sysgen\masterScript37238.pl line 702 Reported by: Unspecified

 

  At first ,I suppose this problem is occured by the VM memory ,so  i set the virtual memory to 1024M,and set the coregenerator's preference ----memory avalible for java to 512M. but this error occured as  the same . Neither did  i set the virtual memory to 1024M,and set the coregenerator's preference ----memory avalible for java to 1024M.

 

 Then  ,I creat a new design ,and just add a xilinx blockset "system generation",double-click the mouse on block "system generator" ,used its default setting, click "generate", but occuerd problem as all ,the details is shown as follows:

 

Begin generation
Checking model status
Checking simulation times
Performing compilation and generation

*** ERROR ***

Errors occurred during netlist generation.
Error using ==> xlProcBlockElaborateBMM at 19
synopsis file 'E:\netlist\synopsis' not found

 

my matlab is installed in C:\matlab,so there is no space in installation-direction . My ISE is installed in C disk ,and my design is saved in E disk.

 

 I doubt maybe this two problems can be solved together.?  ??

 

please help me ,

thanks.

It has been resolved.by set environment  variables _JAVA_OPTIONS = "-Xmx512m" .

But I don't understand why i can''t set it  _JAVA_OPTIONS = "-Xmx1024m",for my personal computer has 3.37 G physics memory ,and set the virtual memory as 2000M.

I am facing the same problem.  However, I do not understand how set the enviroment variables.  I am using windows 7 x64.

System Properties ==> Environment Variables ==> Add New Veriable named _JAVA_OPTIONS with value -Xmx512m but it does not work (I do not think it is what you meant by set enviroment vairables).

 

Please help me, I burn my old board. I ordered new Spartan 6 board and now I am stucked
