Scan Test Power Normalization Using Hierarchical Test Flow

October 07, 2015, anysilicon

Introduction
 
Low power test efforts in SOC design are broadly classified into – fine tuning ATPG patterns, enhancing collaterals for supporting low power ATPG, architecture for low power DFT, improving estimation and correlation. The flow discussed here comes under the category of “fine tuning ATPG patterns”.
 
Currently due

Overview and Dynamics of Scan Chain Testing

May 20, 2014, anysilicon

This is a guest post by Naman Gupta, a Static Timing Analysis (STA) engineer at a leading semiconductor company in India.

In accordance with the Moore’s Law, the number of transistors on integrated circuits doubles after every two years. While such high packing densities allow more functionality to be incorporated on

My Golden Rule for Chip Production Testing

March 10, 2014, anysilicon

Chip production testing is probably the most underestimated task by ASIC development engineers. And yet, testing is an essential step with a direct impact on final chip cost.
 
Let’s start with the basics. Testing of chips is necessary because the chip manufacturing process cannot provide 100% yield. Silicon foundries

Six ways to improve chip yield rate- before the project starts

February 11, 2013, anysilicon

Early on in Chip projects, yield is not taken very seriously. The common thinking goes –  anyhow there isn’t much to do as this early point of time. However, there are actually several things you can do even before the Chip design starts, which will translate to clear savings.

Semiconductor Assembly and Test Services (SATS) Market and Leaders

January 28, 2013, anysilicon

Semiconductor Assembly and Test Services are converting rapidly into a pure outsourcing mode of operation. While today perhaps only 50% of the market is using Outsourced Semiconductor Assembly and Test (OSAT, or SATS) this number is set to increase in the future.
While many of the low-end suppliers are competing
