(Reuters) -Britain's competition regulator on Wednesday cleared chip-design-software maker Synopsys' ( SNPS ) $35 billion deal to buy Ansys ( ANSS ) after accepting certain remedies from the companies.

The regulator said it would not refer the proposed acquisition to an in-depth phase-2 probe.

The watchdog had said in December the deal could reduce innovation and lead to higher prices, but could be approved if the companies resolved those concerns.

Synopsys ( SNPS ), which makes tools for chip design, announced its cash-and-stock deal for Ansys ( ANSS ) in January. The target company's software is used to make a wide range of products, from airplanes to tennis rackets.
