Error while converting a sine PWM block in simulink to HDL code

I have simulated a sine pwm block in simulink. Using HDL code generator I have tried to generate the verilog code for the Altera/Cyclone II target board. The code generation failed at the RTL code generation step. The error message is:
".\emlinterface\EMLInterfaceForHDL.cpp:375:"
"Stopping compilation due to the active MATLAB code errors"
But the block run perfectly in the simulink and I have verified the waveform in the simulink scope.
Any idea what could be wrong?

Nothing seems out of line with your description. At this point I would recommend opening a case with MathWorks Technical Support. Since the error appears when moving from one to three instances, I would concentrate on that. Revert back to one instance; ensure you can generate code. Add a second, with no additional connecting logic; does that work? Add whatever extra logic you need in your design for interconnecting the two; does that work? If you can provide technical support with two similar models, one that works and one that fails MathWorks will have a easier time fixing the issue. In addition, if you understand where the issue originates from you may be able to choose a slightly different implementation, a different block or block configuration, that works around the problem.

I also have a research in PWM in FPGA use HDL coder, may be I have some experiments to help you. Can you send this block into my email: dungdkt27@gmail.com ?

See the attached example on how to generate square wave pulses at regular intervals. The waveform parameters, Amplitude, Pulse Width, Period, and Phase delay, determine the shape of the output waveform.
