- New Memory Map Option "Array Access Guard"

Generate Fixed Point Report Enhancements Aid in Achieving Higher Performance
- Variables List Report
- Loops List Report
- Operators List Report

New GUI Support for LogiCORE Parameters
For VHDL flows, inferred LogiCORE parameters can now be changed from the AccelDSP GUI. As shown below, simply select the associated operator from the Project Explorer window or the Fixed Point Report, then change a parameter (like Latency) in the Properties Viewer window.

Generate Fixed Point Report Enhancements Aid in Achieving Higher Quality of Results
For details on enhancements to the fixed point report, see the AccelDSP Synthesis Tool User Guide section titled AccelDSP Enhancements.

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

General Issues
- 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).
- Why does the FFT example design fail the verify RTL step when using ISE Simullator as the HDL Simulator? See (Xilinx Answer 32222)
- Why do I receive an error message that libSecurity.dll cannot be found when launching AccelDSP? See (Xilinx Answer 32507).
