Time for FMEDA Reuse?

 July 7th, 2022 - By Stefano Lorenzini

Making it easier to integrate configurable IP into safety-critical systems.

How do designers quantify safety in electronic systems? Through one or more tables called Failure Modes, Effects and Diagnostic Analysis – FMEDA. In fact, an FMEDA does not have to be a table; it could be manifested in scripts or some other form, but a table is the easiest way to think of this information. Think of an FMEDA for an IP, as the concept extends easily to a system-on-chip (SoC). The table has a row for each failure mode that the IP experts can imagine might lead to a critical safety problem. Following identifying information for that failure mode is a description of the effect – the safety problem it might cause. Through fault simulation, the safety engineer determines the likelihood of the root cause problem leading to that effect. If the likelihood is significant, the designer will propose a mitigation technique, such as a parity check to detect the problem or an error-correcting code (ECC) check to correct it. A completed FMEDA then represents a comprehensive safety quality document for that IP, a characterization that an SoC integrator can use when determining the FMEDA for the whole design.

Advanced SoC Interconnect IP Enables Greater Flexibility in an Era of Consolidation

I am thoroughly enjoying 2013. That’s because there seems to be a lot more reason for optimism this year than last year.  But before we let go of 2012, it’s important to reflect on the past year and see what it can teach us so we can make better business decisions moving forward.

MIPI LLI or C2C?

Two new options for interchip connectivity are available today that enable sharing a DRAM memory between two chips for data and programs. These standards, called MIPI Low Latency Interface (MIPI LLI) and Chip-to-Chip (C2C), are primarily targeted at mobile phones, where a mobile phone’s modem usually requires its own discreet DRAM. With either C2C or MIPI LLI, the mobile phone modem can use the application processor’s DRAM though a low-latency, memory-mapped connection that requires no software drivers or runtime software.
