Firstly, Apu, in English the word "buyout" is a noun, not a verb. "Whou would buyout..." is gibberish. Either "Who would buy..." or "Who would buy out..." (note the space).
Secondly, are you insane? Buy out Synopsys? Expecting someone to acquire Synopsys is like expecting someone to acquire Microsoft. There's no one related to EDA world with enough resources to buy out such a huge company.
