Hi Tricky!
you are right there are errors.
Actually dsp builder use library 'dspbuilder' that I think modelsim do not have.
As i am using modelsim Starter edition 6.5e (it is for use with altera software v10.0).But i want to use it for simulation of quartus II and dsp builder v6.0
In my simulation design DSP Builder v6.0 I have used deinterlacer,chroma resampler, color space converter and scaler megacore functions.(dsp builder 10.0 or 10.1 do not have these vip megacore functions) altera shifted these megacore functions to Quartus II 10.0 or 10.1.
please let me know if there is a way to use modelsim-altera Starter edition 6.5e dsp builder v6.0!!!!!
