The Parallel Pain

The Parallel Pain

Parallel busses are a pain to implement.  They really are.  Sure, they are slower than blazing-fast SERDES busses, but they…

Interconnect loss modeling?  Check.  Signal conditioning modeling?  Check.  Ability to simulate multiple S-parameter models for things like connectors and packages…

Know your limits

Know your limits

“A man’s got to know his limitations” … true, and so does a digital bus.  Clint Eastwood’s quote to conclude…

Stupid vias… {grumble grumble}

Stupid vias… {grumble grumble}

Yeah, I can totally see Homer Simpson designing his SERDES bus and getting frustrated by all the additional insertion loss…

Via modeling – what do I really need?

Via modeling – what do I really need?

The whole via simulation issue is admittedly complicated, and I think really boils down to whether the vias are single-ended…

Whether you are trying to correlate simulated waveforms to measured waveforms for a DDR3 signal, or board timing numbers for…

Your traces aren’t square, but do you need to care?

Your traces aren’t square, but do you need to care?

Yes, you should care about the fact that PCB traces, when actually manufactured, end up having more of a trapezoidal…
