Software Support

- What software is required to install AccelDSP Synthesis Tool? See (Xilinx Answer 17966).

AccelDSP Synthesis Tool Enhancements

LogiCORE IP Core mapping

- This release is the first to support the use of highly optimized Xilinx LogiCORE IP Cores during RTL generation.

- The multiplier core is the first core that is supported, with more cores to follow in future releases.

- This feature is controlled by means of the following new project option: SetProjectOption -use_logicores 1.

Increasing Fmax

- To reduce critical paths that occur at the output port of a memory, AccelDSP can automatically add a register to increase the maximum frequency.

- This feature is controlled by means of the following new project option: SetProjectOption --memmap_defaults {{register_output 1}}.

MATLAB 2008a

MATLAB 2008a is now supported by AccelDSP. For information on switching versions of MATLAB, see (Xilinx Answer 22966).

General Issues

- How do I switch between MATLAB versions used with AccelDSP? See (Xilinx Answer 22966).

- Is there a way to terminate or kill a process once I have launched the next step in my design flow? See (Xilinx Answer 31602).

- When running the Generate RTL step, error messages occur (because of certain coding styles): "E-ERR-0009): Failed to generate RTL model from fixed-point design for unknown reasons!" or "Out of memory." See (Xilinx Answer 31098).

- When I launch AccelDSP, why do I receive "Error: Could not load the syntax highlighting File.invalid command name "AppInfo::Appinfo" while executing "Appinfo::Appinfo ProductDir"? See (Xilinx Answer 30695).

- AccelDSP appears to hang when I launch it, or it takes a long time to initialize. See (Xilinx Answer 31293)

- Why do my Hardware Co-Simulation targets disappear after installing the DSP Tools 10.1 Service Pack 2? See (Xilinx Answer 31389).
