sed tutorials & labs.

The most practical sed path for VLSI — built around real RTL/DV/PD workflows, not generic Linux text-processing. From the stream-edit / pattern-space mental model through basic substitution, RTL filelist rewrites, simulator-script edits (VCS / Xcelium / Questa), line filtering, regex, in-place editing safety, configuration management, synthesis / STA flow maintenance, report cleanup, UVM log normalisation, hand-offs to Bash / awk / Tcl / Python, mass RTL refactoring (signal / module / include / define renames), defensive debugging, five industry case studies (filelist migration, RTL path migration, simulation-script upgrade, constraint updates, regression cleanup), tiered interview mastery, five pre-merge review checklists, and the misconceptions that hold engineers back.
