Israeli chip designer backs Zebu for SoC validation
Xsight Labs in Israel is using a 7bn gate ZeBu Server from Synopsys for the validation of its X1 25.6Tbit/s intelligent networking switch processor.

Xsight has used the ZeBu server for pre-tapeout validation of complex networking workloads with full system-on-chip (SoC) emulation of the chip, which includes 100G PAM4 SerDes. The performance has also enabled full system software driver development and maximum utilization of all X1's Ethernet ports for networking performance validation.

"Xsight Labs uses a comprehensive set of tools to ensure we are delivering best-in-class networking switch silicon to our customers. Synopsys' ZeBu Server 4 cloud solution is an integral element of our verification methodology, which has provided our verification team with convenient, remote access to the high capacity required for full SoC emulation to perform extensive networking validation testing," said Erez Shaizaf, co-founder and Switch General Manager at Xsight Labs, headquartered in Kiryat Gat, Israel. "By using ZeBu Server 4 throughout the critical development process, Xsight Labs has been able to identify potential issues before releasing the X1 family of 25.6Tbit/s and 12.8Tbit/s fully programmable data centre switches to our customers."

In addition to ZeBu Server 4, Xsight Labs adopted various Synopsys DesignWare IP to meet the memory, connectivity and processing requirements of the 25.6T X1 networking switch SoC.

The company emerged from stealth in December and in March raised $8m in its Series D funding round led by Valor Equity Partners and Atreides Management with Fidelity Management & Research Company. Existing investors Battery Ventures, Intel Capital, M12 Microsoft’s Venture Fund and Xilinx, increased their investments. Additionally, Accton Technology joined as a new strategic investor.

“Xsight Labs’ Series D was significantly oversubscribed and is the largest round ever raised by our group,” said Avigdor Willenz, Xsight Labs’ founding investor. “The completion of this round will help Xsight Labs execute its ambitious vision of delivering end-to-end connectivity solutions for cloud infrastructure.”

Synopsys points to a power consumption that is ten percent of other emulation systems for its ZeBu Server 4 with capacity up to 19bn gates. Last month both
