Renesas Solves High-Level Verification Challenges Using Formal Equivalence Checking


A team at Renesas Electronics Corporation found that they were significantly reducing the time advantages of their High-Level Synthesis flow due to bugs in their SystemC code and equivalence problems due to design changes. It was taking too much time to find and debug these issues and some bugs were slipping into the generated RTL. To solve these challenges, they added SLEC®, which is the form... » read more

Aligning Automotive Safety Requirements Between IP And SoCs


Today’s SoCs for automotive safety-related systems integrate numerous IP blocks. At the system level, the Hardware Software Interface (HSI) between these IP blocks needs to be verified in simulation and validated in prototype. However, the scaling of the scope and effort to verify or validate is not linear based on the growing complexity of SoCs and their components such as IP. Depending on t... » read more

Analog Simulation At 7/5/3nm


Hany Elhak, group director of product management at Cadence, talks with Semiconductor Engineering about analog circuit simulation at advanced nodes, why process variation is an increasing problem, the impact of parasitics and finFET stacking, and what happens when gate-all-around FETs are added into the chip. » read more

Week In Review: Design, Low Power


Xilinx filed a patent infringement countersuit against Analog Devices, alleging infringement of eight U.S. patents including technologies involving serializers/deserializers (SerDes), high-speed ADCs and DACs, as well as mixed-signal devices targeting 5G and other markets. The counterclaims are in response to Analog Devices' December lawsuit alleging unauthorized use by Xilinx of eight ADI pate... » read more

Dealing With ECOs In Complex Designs


Namsuk Oh, R&D principal engineer at Synopsys, talks about the impact of more corners and engineering change orders, how that needs to be addressed in the flow to close timing, and how dependencies can complicate any changes that are required. » read more

Week In Review: Design, Low Power


Inphi Corporation and Synopsys finalized the acquisition of eSilicon. Synopsys acquired certain IP assets from eSilicon, including TCAMs and multi-port memory compilers, as well as its Interface IP portfolio with High-Bandwidth Interface (HBI) IP and a team of R&D engineers; it did not disclose terms of the deal. Inphi Corporation bought the rest of the company for approximately $216 millio... » read more

Blog Review: Jan. 15


Cadence's Paul McLellan looks back at the history of lithography, from its fundamental equation to multiple patterning and the challenges facing EUV today. Synopsys' Taylor Armerding warns that medical device security isn't keeping up with new threats, despite positive steps, due in part to lack of funding, delayed initiatives, and a focus on critical service delivery. In a video, Mentor'... » read more
