MATLAB and SimuLink Interaction
(Xilinx Answer 31933) - Why do I receive an error message stating "continuous sample times are not allowed" when driving a Simulink Spectrum Scope with Xilinx System Generator blocks?
(Xilinx Answer 21750) - Why do I receive a "xlSimulationRequired" or "Reference to a cleared variable sysgen_return_status" error when I try to generate the design?
(Xilinx Answer 23000) - An indeterminate input data (also known as a NAN) error occurs when design is simulated.
(Xilinx Answer 24616) - Why am I unable to access the quantization parameters in the FDATool in System Generator?
