====== Digital Logic ======

This lecture crosses the elusive software - hardware barrier and exposes the basic building blocks of hardware. It also introduces the hard design language, Verilog.

===== Outline =====

  * Semiconductors
  * Transistor switches
  * Logic Gates
  * The universality of AND/OR/NOT
  * Boolean Expressions
  * Building combinational circuits: adders, multiplexors, the ALU
  * Circuit verification via Verilog.

===== Big Ideas =====

  * Complex logic can be realized using a hierarchy of layers each adding more complexity to the one before it
  * The journey from On/Off to arithmetic and decisions 




===== To Do =====

  * Read Sections B.1 to B.5 of Appendix-B. If you have the old edition of the book, read Section 4.5 upto page 241 and Sections B1-B.3.
  * Go over the file, ''Adder.v1'' in the //Resource Directory//
  * Do the tasks of LabK
