BRUSSELS, Dec 11 (Reuters) - Chip design software

company Synopsys ( SNPS ) has offered to sell an Ansys ( ANSS )

unit on top of one of its own in a bid to win EU approval for

its $35 billion acquisition of the chip design software company,

three people with direct knowledge of the matter said.

The European Commission, which acts as the European Union's

competition watchdog, is now seeking feedback from rivals and

customers on Synopsys' ( SNPS ) proposal, with a Dec. 16 deadline for

responses, the people said.

Synopsys ( SNPS ) has said it would sell its optical design tool

maker Optical Solutions Group to design and emulation company

Keysight Technologies ( KEYS ), subject to the Ansys ( ANSS ) deal.

It has now also offered to divest Ansys PowerArtist,

including its research, developing, distributing, licensing,

selling and marketing. PowerArtist is a tool used to analyse and

reduce power to enable power-efficient design.

Synopsys ( SNPS ) did not offer any behavioural remedies related to

its business practices, the people said, which would suggest the

EU antitrust enforcer does not have any concerns about

interoperability and product bundling following feedback from

industry players last month.

Ansys' ( ANSS ) software is used in creating products ranging from

airplanes to tennis rackets for players such as Novak Djokovic.

The Commission is scheduled to decide on the deal, the

biggest in the technology sector since Broadcom's ( AVGO ) $69 billion

purchase of software maker VMware a year ago, by Jan. 10.
