+ve/-ve voltage source

I want to create an astable m/vibrator that has a 30V p/p swing using a +15v/-15V supply.

Is there a way/tool/design element to create a +ve and -ve voltage source in the same circuit?

thanks

Tony

Call up 2 dc voltage sources: Connect the (-) terminal of one to ground and the (+) terminal is +ve. Connect the (+) terminal of the other to ground and the (-) terminal is -ve.
