About Chandra Mohan Gupta Vissamsetty

Overall experience in semiconductor industry - DFT(ATPG/GLS/post Siliocon debug/coverage debug/scan insertion/pattern retarget) and Tool Automation using perl/shell/tcl. • Experience DFT concepts and methodologies, about usage of industry with standard Mentor Graphics tools. • Responsible for partition/region level/soc level ATPG and GLS. • Experience in pattern retarget from partition level pattern to soc level and simulate them.• Good in Silicon debugging chain, stuck at and at speed using tessent diagnosis along with PT session/ mff and analyzing schmoo plot analysis. • Good in Gate level simulation(GLS) on timing(with SDF) and no-timing patterns for stuck at, atspeed and path delay fault models using VCS tool. • Experience in ATPG for stuck at/Transition and path delay fault models and coverage debug analysis by using Testkompress tool. • Cell aware Atpg Fault modeling for St@/@Speed.• Good understand in timing concepts, aware of Constantins in sdc and usage of SDF files in simulations.• Experience in FE/BE SpyglassDFT / insert-DFT Debug – DRC analysis and fixing in DC/FC Environment.• Experience in.lib and sdf file generated different pvt corners.• Developed/Expert in automation flow for DFT using Scripting languages like PERL, Shell and TCL.Experience in jtag, bscan,ijtag,SSN.• Good in STA and CMOS concepts.• Conducted hands on training sessions on perl scripting for a team 30-40 people.
