System Generator for DSP 9.1.01 is a minor update. Please read the documentation, as it answers questions you might have about changes to the functionality or the look from previous versions of System Generator for DSP. The System Generator User Guide (PDF Version) is accessible from: http://www.xilinx.com/ise/optional_prod/system_generator.htm
- How do I enable Virtex-5 SXT support or other devices installed to ISE after System Generator was installed? See (Xilinx Answer 24158).
Xilinx Block Set Issues - Why does the System Generator for DSP 6.3 or 7.1 design (which passed generics to the black box for port widths) fail in System Generator for DSP 8.1 or greater? See (Xilinx Answer 22715).
- Why does XST fail to find a signal which System Generator has placed a constraint on in the XCF? See (Xilinx Answer 25016).
- Why does the design fail to generate when using a FIFO block, From FIFO block, or To FIFO block in the design, and the target path is more than 160 characters? See (Xilinx Answer 23614).
- Why do the outputs of a FROM and TO register appear to be incorrect when I use the Free Running Clock with Hardware in the Loop (HITL) Co-Simulation? See (Xilinx Answer 23206).
- Why do I receive a timeout error when using the Shared Memory or Shared FIFO blocks in a design? See (Xilinx Answer 24288).
- Why do I receive the error message "All Xilinx Blocks must be contained in a level of hierarchy with a System Generator Token" when I use the multiple subsystem generator flow or have my token in a subsystem? See(Xilinx Answer 24845).
General Issues - Generation fails when the Simulation Stop Function is defined for a model. See (Xilinx Answer 18623).
- User Hardware Co-Sim files disappear when installing System Generator for DSP update. See (Xilinx Answer 18646).
- How can I improve the synthesis results of the clock wrapper clock enable logic? See (Xilinx Answer 23253).
- Why do I receive "Error evaluating 'OpenFcn' callback of Xilinx Block. Error using ==> xlOpenGui" Cannot parse XLM file" when I try to open a SysGen block on a network installation, or after installing a new version. See (Xilinx Answer 23223).
- Why do I receive "Error 0001: caught standard exception" error" when using IBM Clear Case? See (Xilinx Answer 24263).
- Why do post-PAR simulation mismatches occur when running a design at faster than 200 MHz? See (Xilinx Answer 24268).
- I cannot generate an NGC, Bitstream, Timing Analysis, or Hardware in the Loop target when using Synplify as my synthesis tool. Why? See (Xilinx Answer 24273).
- Why do I see an instantiated register called "xlpersistentdff" in a System Generator for DSP design? See (Xilinx Answer 24257).
- Why do I receive the error message "All Xilinx Blocks must be contained in a level of hierarchy with a System Generator Token" when I use the multiple subsystem generator flow or have my token in a subsystem? See (Xilinx Answer 24845)?
- When I generate a design using "with testbench," the Verilog testbench does not show up in the generated ISE project. (Xilinx Answer 24865).
- Why do I receive the error message "standard exception: XNetlistEngine" when I try to generate a design containing the FIFO block for a Spartan-3E device? (Xilinx Answer 24866).
- When my model is opened with MATLAB 2006b from Windows Explorer by double-clicking the model, I receive an internal error when I try to simulate. (Xilinx Answer 24867).
- I am having some problems running Network-based Ethernet Co-Simulation with the ML506 board. (Xilinx Answer 24868).
