Design Reviews Surveys Consulting

HW/SW Engineering (Eagle, KiCad, VHDL, Verilog, Ada, Linux)

Agenda

Day #1● schematic capture● defining net classes● electrical rule check

(ERC)● schematic structure● exercises & consulting● preparing PCB layout● outlines of the board● fiducials, mounting holes

Day #2● part placement● texts in copper● silk screen● design rules (DRC)● layer setup, via types● routing● communication with

suppliers and assembly houses

Day #3● creating/editing parts in

the library● symbols, packages,

devices● library structure● naming conventions● resource management● CAM processor● Gerber/drill data● exercises & consulting

Day #4● project & schematic structure● practicing with modular and hierarchic designs● naming conventions / style guides● introduction to agile HW development● design for test & manufacturing (DFT/DFM)● scripting & automation
