The first article is here. This article will use the detail mmRadar analysis and semiconductor for analysis.

First: Vehicle level requirements

It is the perception system will inherit following vehicle level requirements, we take the architecture of 'CAST safety Analyze for Automated Vehicle Life-killing Accident', for following configuration:

Second: High automated driving functionality requirement

ASIL	ID Functional Safety Requirement	Functional Safety Requirement	Safe State	FTTI
B	FSR_04_01_02_01	Velodyne HDL-64E S3 will not mistake surroundings and trigger unexpected disengagement commands	Velodyne HDL-64E S3	etc
B	FSR_04_01_02_02	Installation and wiring of HDL-64E S3 will not mistake surroundings and trigger unexpected disengagement commands	Installation and wiring of HDL-64E S3 will not mistake surroundings and trigger unexpected disengagement commands	etc
B	FSR_04_01_02_03	Vertical FOV within HDL-64E S3 will be enough for monitoring surroundings and not trigger unexpected disengagement commands	FOV vertically 26.8deg	etc
B	FSR_04_01_02_04	Digital signal processing and waveform analysis for accuracy, extended distance sensing and intensity data are not well enough for monitoring surroundings and not trigger unexpected disengagement commands	HDL-64E S3	etc
B	FSR_04_01_02_05	HDL-64E S3 shall ensure Laser emitters and receivers are positioned as following photo, and ensure the outer case can ensure IP67, and anti-against dust, rain, snow pollution	HDL-64E S3	etc
B	FSR_04_01_02_06	HDL-64E power supply shall have mechanisms protect itself from unintended interruption, so that the monitoring capability will be continuously open	HDL-64E power supply	etc
B	FSR_04_01_02_07	HDL-64E Ethernet shall have mechanisms protect itself from unintended message corruption, so that the monitoring capability will be continuously open	HDL-64E Ethernet	etc
B	FSR_04_01_02_08	HDL-64E shall have mechanisms to anti-against wrong calibratioin parameters included in-stream from the sensor or from the included data files leading to performance degradation, incorrect behavior	HDL-64E	etc
B	FSR_04_01_02_09	HDL-64E shal have mechanisms to choose and protect correct run-time parameters from RS-232 serial port	HDL-64E	etc
B	FSR_04_01_02_10	HDL-64E shall have proper spin rate and configured inside flash memory, RAM	HDL-64E	etc
B	FSR_04_01_02_11	Laser firing sequence and timing shall have mechanisms to determine the exact firing time for each laser so as to properly time-align with the other data sources	HDL-64E	etc
B	FSR_04_01_02_12	HDL-64E shall have mechanisms to protect firmware updates from corruption	HDL-64E	etc
