President Donald Trump’s administration has lifted recent export license requirements for chip design software sales in China, as Washington and Beijing implement a trade deal for both countries to ease some restrictions on critical technologies.

Shares of Synopsys and Cadence Design Systems jumped on Thursday after the United States lifted export restrictions on chip design software to China, easing major uncertainty around access to the crucial market.

Siemens, Synopsys and Cadence – three of the world’s largest EDA software developers – are set to resume sales to China.
