Typically, there is an existential rift between the on-chip access requirements for test and the need for security in SoCs. Using traditional deterministic scan techniques has meant opening up full read and write access to the flops in a design through the scan chains. Having this kind of access easily defeats the best designed… Read More

Observation Scan Solves ISO 26262 In-System Test Issues
Automotive electronic content has been growing at an accelerating pace, along with a shift from infotainment toward mission critical functions such as traction control, safety systems, engine control, autonomous driving, etc. The ISO 26262 automotive electronics safety standard evolved to help ensure that these systems… Read More
Physically Aware DFT Improves PPA
Introducing on-chip test circuitry has become a necessary criteria for an ASIC’s post manufacture testability. The test circuitry is usually referred as DFT (Design-for-Test) circuit. A typical methodology for introducing DFT circuit in a design is to replace usual flip-flops with special types of flip-flops called ‘scan… Read More
