What We Do

LogicVision has three basic product lines that operate in unison for yield learning.

LogicVision’s Yield Learning Process

LogicVision’s silicon test solution, ETCreate, inserts test structures, called “eyes in the die”, at strategic locations throughout the SoC. The “eyes” test the device’s memory, logic, and analog circuitry as well as interconnects and timing parameters. These “eyes” continue to monitor for defects throughout the entire life of the chip, from initial design debug through manufacturing and into the final system product.

For silicon debug, LogicVision’s Silicon Insight is the "magnifying glass" used to uncover the failure details observed by the eyes. It interrogates the eyes to identify and characterize the source of failures or problems within the chip. Since it’s interactive, it can take feedback from the “eyes” and then direct the eyes to explore every path and component of the device structure.

Finally, for silicon analysis, Yield Insight interacts with Silicon Insight to collect test results from multiple devices. It looks for systematic failures across a wide range of process parameters and operating conditions. Yield Insight then provides immediate, actionable information for yield learning.

What is the value?

The value of LogicVision’s technology is a much lower cost of test, dramatically faster time-to-yield, and considerably fewer field returns. Additionally LogicVision’s yield learning process results in semiconductor manufacturers achieving the steepest yield learning ramp possible.

This is all made possible by the actionable information resulting from the yield learning process. It may include changing the device specification or modifying the end-application requirement. It could suggest tightening the fabrication process or modifying the design. It might even propose living with current yields, but alerting designers so they can consider changes in future designs, thus eliminating the current problem. Overall there is an increased profit potential for the product and a significantly higher ROI.
