Hello, Dear Readers, In this post, I will share some deep insights into regular pattern searching using grep, awk, and sed. In VLSI/EDA flows, engineers frequently work with large Innovus, Voltus, STA, EMIR, synthesis and simulation reports. Linux commands such as grep , awk , and sed provide a fast way to search, filter and process this data without opening huge files manually. 1. Regular Expressions: A regular expression (regex) defines a pattern for searching text. Common patterns: Pattern Meaning Example . Any character V.D * Zero or more ab* + One or more ab+ [0-9] Digit U [0-9] [a-z] Lowercase [a-z] + ^ Start of line ^VDD $ End of line VDD$ ` ` OR `VDD VSS` For example: grep -E 'ERROR|WARNING|FATAL' voltus.log Searches for any of the three patterns. 2. grep — Search and Filter: grep is mainly used to find matching lines . Basic search grep 'VIOLATION' report.rpt Case-insensitive search grep -i 'error' run.log Show line numbers grep -n 'VIOLATION...
Hello Dear Readers, Today in this post I will provide some deep insight into what is happening in the semiconductor industry. So I hope you like it and enjoy it to improve your knowledge and awareness about the industry. So let's start it today we are discussing, The Importance of 3D IC Ecosystem Collaboration in the VLSI Market. As design teams continue to develop new generations of transformative products, the demand for computing remains relentless. Modern workloads have brought packaging technologies to the forefront for innovation and pushed the boundaries for silicon product design in terms of product performance, function and cost. Not too long ago, packaging technologies were thought of as inconvenient back-end processes. But times have changed, and rising advancements in artificial intelligence, big data, cloud computing, and autonomous vehicles have pushed the computing envelope unlike ever before (along with the need for packaging technologi...
