ISE13.1和matlab2012a能匹配吗？SysGen在simulink中仿真出错

用System Generator 时，生成verilog代码时，提示出错，An internal error occurred in the Xilinx Blockset Library。好像是软件设置问题，不是设计问题。
在xilinx官网上搜索解决方法。按照说的不能解决问题。连软件自带的mdl example 文件，生成verilog代码时都报错。
无意看到ISE 和Matlab的匹配，说是ISE13.1 支持MATLAB R2010a 或 R2010b 。ISE13.4支持R2011b。不知道是不是存在兼容性问题。
初到论坛，多多指教！

另外问题如下：
An internal error occurred in the Xilinx Blockset Library

Since it is possible that this internal error resulted from an unhandled usage error in your design, we advise you to carefully check the usage of the block reporting the internal error. If errors persist, we recommend that you restart MATLAB.

xilinx 网站解决办法如下，但是试过了都没有。
Solution                       
This error can occur for a variety of reasons. Below are some common examples and the resolution needed:
There is a space in the System Generator installation directory. Re-install the System Generator without a space.Avoid a deep installation directory.
There is a space in the MATLAB installation directory. Re-install MATLATB without a space.
The way MATLAB was invoked. Open up the System Generator via the sysgen token.Ensure that the XILINX environment variable is set and that the PATH includes $XILINX/bin/nt; $XILINX/lib/nt before launching MATLAB.
There is an issue with M-Code processing. Check that the "$TEMP" environment variable is accessible and that the temp directory is not full.
The cache is too full. Read the System Generator for DSP User Guide (UG640) to see how the cache is cleared and see (Xilinx Answer 37984).The temp directory could be full or not accessible.Change the permissions and use the system tools to empty the temp directory.
License checkout failed. Ensure that the XILINXD_LICENSE_FILE environment variable points to a valid Xilinx.lic file.
