Tcl tutorials & labs.

The most practical Tcl path for VLSI — built around real synthesis / STA / SDC / PD workflows, not generic Tcl content. From the Tcl-as-command mental model and the substitution / braces / quotes triad through control flow, procedures, file I/O, regex, EDA collections, SDC fundamentals, synthesis scripting, sign-off STA, physical-design Tcl, report parsing, multi-corner multi-mode flows, design-database querying, defensive debugging, verification do-files, hand-offs to Bash / Make / Python, six industry case studies (synthesis runner, STA sign-off, SDC generator, violation extractor, PD collector, Questa wave setup), tiered interview mastery, seven pre-tapeout review checklists, and the misconceptions that bite real engineers.
