Customer challenges in achieving functional safety Vol. 2

"Various problems occur when developing an automotive ASIC/ASSP (Application Specific Standard Product) that meet the design compliance of the ISO26262 functional safety standard. This blog will introduce the flow from Automotive Safety Integrity Level, ASIL determination to safety mechanism specifications creation, and describe the issues and countermeasures in the flow we often share with our customers."

RISC-V core UVM verification

"In general, CPU core development requires many more man-hours for the verification phase than the design. This is because there are a huge number of items to be verified, such as the instruction sequences and the combination of exceptions and error occurrences. This blog introduces an example of RISC-V core UVM verification that Verification Technology USA, Inc. (Vtech) provided a startup company in the US as a service."

Timing is everything: from punch lines to software development

"As the hardware comes together, software teams port their code and begin functional testing, along with timing analysis. Multiple cores and IP result in different teams accessing the hardware – often independently and then grouped together.  Trouble can occur within one module and more often between modules with different clocks, latency, etc."

Effective Validation Method of Safety Mechanism Compliant with ISO 26262

“The metrics to measure the effectiveness of Safety Mechanisms include code coverage rate, SPFM (Single- point failure metric) and LFM (Latent failure metric). Especially in SPFM and LFM, if the specified value is not reached on the Fault Injection Simulation (using Gate Level) at the end of verification, it will cause iterations”
