Calterah Selects Synopsys’ IP to Develop mm-Wave Automotive Radar Chipsets

Synopsys and Calterah Semiconductor, a developer and designer of CMOS mm-Wave radar sensor ICs, have announced that Calterah's new-generation of advanced CMOS millimeter-wave (MMW) radar system-on-chips (SoC) that integrate Synopsys' DesignWare ARC EM Processor IP, have entered the mass production phase. 

The new-generation of Alps 77/79 GHz chips boast higher speeds, flexibility, user-friendliness and reliability to deliver more competitive chip solutions for automotive millimeter-wave radars. With Synopsys' functional safety-compliant ARC EM Processor IP, Calterah will continue providing its global users with higher-performance, easier-to-use, and lower-power MMW radar technology to create a safer, smarter environment for drivers and their passengers.

Calterah's Alps chip series includes four transmitter channels at most, four receiver channels, a highly configurable waveform generator, and an analog-to-digital converter with sampling rates of up to 50 million of samples per second (MSPS). The complete, efficient signal processing baseband implements classical radar algorithms in hardware and saves development resources by delivering a solution with lower power consumption and higher performance. In addition to the conventional embedded wafer-level ball grid array (eWLB) package, the Alps chip series also includes an Antenna in Package (AiP) solution, which greatly reduces the difficulty and cost of radar development by integrating the antenna onto the chip packaging layer. This diverse lineup of next-generation products provides users with a complete set of solutions covering long-range, medium-range, short-range, and ultra-short-range radar solutions.

Calterah implemented an ISO 26262 functional safety development process to help ensure the Alps chip series met the standard's ASIL B requirements for automotive safety. This included conducting functional safety-related monitoring and detection on more than 190 blocks in the design and analyzing over 1,000 failure modes, leading to the development of dozens of chip-level safety mechanisms. By using Synopsys' ASIL-compliant ARC EM6 Processor, Calterah successfully reached its target functional safety ASIL level while enhancing overall processing performance and power efficiency for its Alps automotive radar SoC.

Synopsys offers a broad portfolio of automotive-grade DesignWare IP that is ASIL ready, is ISO 26262 certified, meets stringent AEC-Q100 reliability standards, and supports automotive quality management to help accelerate the development of ADAS, connected vehicle and infotainment, and MCU designs. The ASIL-compliant DesignWare ARC EM Processor integrates hardware safety features and safety monitors to detect system errors.

Advanced automotive ADAS SoCs require massive amounts of data processing to accommodate a range of functions such as radar, LiDAR, and sensor. Synopsys provides companies such as Calterah with the industry's broadest portfolio of silicon-proven, ASIL Ready IP including differentiated ARC Processors that address the functional safety, reliability and quality requirements of automotive systems.
