The auto industry’s increased use of on-board electronics for guidance, entertainment and safety control systems has created substantial integrated circuit (IC) and system-on-chip (SoC) design challenges to deliver energy and cost-efficient – yet highly reliable – electronics systems. As the use of on-board electronics in vehicles rises, power management plays a more critical role in automobile reliability.
To address power management, microcontroller units (MCUs) and other chips controlling on-board systems require a lower voltage rate to ensure consistent and reliable operations. One solution that addresses this issue is the advanced chip design tool PowerArtist, a register transfer language (RTL) power analysis and optimization platform from ANSYS subsidiary Apache Design. The solution enables design teams to obtain deeper insight into circuit power consumption at an early stage; it also allows implementation of power-optimization techniques. PowerArtist’s proprietary technologies ― PowerArtist Calibrator and Estimator (PACE) and RTL Power Model (RPM) ― help designers both to lower power and ensure power delivery network integrity. Providing early power analysis, power reduction and design optimization assists in meeting power budget requirements and increasing overall power efficiency.
On-board electronic systems can impede each other’s operation due to electromagnetic interference (EMI) noise, which can further compromise reliability. Our comprehensive chip-package-system (CPS) codesign/coanalysis methodology considers the impact of IC on system-wide EMI. The RedHawk full-chip power integrity and sign-off platform analyzes component activity and simulates the electromagnetic excitation it causes via a chip emission model (CEM). Sentinel-PSI and ANSYS SIwave use this CEM to perform systems-level EMI analysis, ensuring that the system design meets near- and far-field electromagnetic field distribution and that the final electronic system is EMC compliant.
