I generated sawtooth waveform from signal generator and repeating sequence, but for a frequency such as 8 Hz, the wave shape is irregular, and for frequencies such as kHz, the waveform is not a periodic one itself.
how high frequency sawtooth can be created ?

I think you have to decrease your fixed step, for 8 Hz set your step time to (1/8)/30, if f is your higher frequency, choose (1/f)/30

k,hope i have to set a fixed step solver in configuration parameters to the whole model...? or by any other way

Yes, in configuration parameters to the whole model

For using variable step solver, increase refine factor in Data Import/Export pane in Configuration parameters

I am new to simulink and i am having the same problem. How can i change the fixed step? I dont know where to find it.
