How to phase shift a triangular waveform

Hello, I would like to generate multiple triangular waveform(4 numbers of carrier waveform) each with a phase shift of 90 degree each. All the carrier should have same carrier frequency(say 1khz).

I have used repeating sequence for the triangle waveform generation and it is working. Which simulink block that I can use for a phase shift of 90 degree? or any other solutions?

Hoping to get a reply soon.

Regards,

Roy
