Synopsys, Ansys rise after China regulator gives conditional approval for $35 billion buyout

** Shares of chip design software provider Synopsys SNPS.O rise 4.1% to $582 premarket and engineering software maker Ansys' ANSS.O shares up 2.8% at $385

** China's market regulator grants conditional approval for Synopsys' $35 billion buyout of peer Ansys

** This clears a major hurdle for the deal, after back-and-forth over U.S. restrictions on export of electronic design automation tools to China had led to concerns over Chinese regulators blocking the deal in retaliation

** The deal, which had already received merger clearance in every jurisdiction other than China prior to this, according to the companies, carries a deadline of July 15 for its closure with an option to extend until January next year

** SNPS shares up ~15.2% YTD, ANSS up ~11% YTD
