Article of the month: “Termination Placement in PCB Design—How Much Does it Matter”,
One of the really critical issues when designing high speed digital PCB’s is what termination strategy to use. Earlier we have featured an article by Doug Brook, UltraCAD inc., on parallel termination in this article he explains the benefits and considerations to be made “up front” when using serial termination. Doug brooks discusses just that and does this in his own straight forward and simple way, so complex theory becomes clear as daylight to the reader.

The October vol. of pcb-update newsltter is now ready for download.featuring the article 
“I/O Designer - Uniting Disparate HDL, FPGA and PCB Design Flows”  
written by Dave Brady & Rick Stroot of Mentor Graphics describing new technology that will smooth the inte
gration between VHDL code and the schematic design tool and the connection of the FPGA to the PCB a process, that only a short while ago was time consuming and very error prone.
