Why do we need a spanning tree in transparent bridging?
Answer:
To eliminate loops in the topology, which confuse bridges and result in frame looping.
How do we design a MAC in an IC? (Describe the general design fl ow and the variables used in programming.)
Design flow: block diagram with input and output signals → state machine of each block/module → Verilog or VDHL parallel hardware programming → synthesized and simulated circuits → layout and tape-out. Variables: program output variables/signals as parallel functions of input variables/signals and local variables/signals.
