    [Moved]: Calibre PEX output additional parameter

    Re: [Moved]: calibre pex output additional parameter Hi,timof Thx. I can't use google anymore a few days ago,so I couldn't login edaboard.com.

    [Moved]: Calibre PEX output additional parameter

    Re: calibre pex output additional parameter Hi,timof Thanks,With your help maybe I had found it. As for the second snapshot:sorry,I can`t find out the netlist anymore,the nelist is about one year ago.And I can`t reproduce it.

    [Moved]: Calibre PEX output additional parameter

    Re: calibre pex output additional parameter Thanks,backannotate this netlist into my layout?It meas compare the netlist and layout（trace the new node in netlist to find out new node location in layout）？

    [Moved]: Calibre PEX output additional parameter

    [Moved]: calibre pex output additional parameter When I use calibre pex,it output some parameters that don`t exist in schematic，such as the pic,the number '4' and the string 'inh_bulk_n' don`t lie in schematic.how can I solve this problem?thx

    Twisted-pair model for HSPICE

    Hi dick_freebird I will research the tline model and how to turn "lumped model+tline model" into one model.

    Twisted-pair model for HSPICE

    Hi FvM and dick_freebird Now I had fabricated about 40 pieces chip and tested it by using category 5 cabling,they communicated with other company's Ethernet controller chip,some failed in 60m length cabling,some failed in 70m length cabling,some failed in 80m length.But if I used category 5e...

    Twisted-pair model for HSPICE

    Hi,dick_freebird I don't have a transmission line model fitted by some customer or anyone else. I'm designing an Ethernet chip which has a 10M/100M PHY.I found a problem when I test it by using category 5 cabling.It work abnormal When the category 5 cabling is longer than 70m.So I need a...

    Twisted-pair model for HSPICE

    I want the properties of twisted pair model it can run like as the real one.Maybe I could build a model by using the HSPICE W-element RLGC model.I will study HSPICE Signal Integrity User Guide.Thanks.

    Twisted-pair model for HSPICE

    Thanks for your answer.I extremely need a Twisted-pair model to do simulation.Do you know where I can find one?Thanks

    Twisted-pair model for HSPICE

    Hi,I'm looking for a Twisted-pair model to do simulation.There is a Twisted-pair model I found in IEEE 802.3 standard.But i don't know it was equivalent to how long twisted-pair in real.50m or 100m or something else? Any help is much appreciated. Thanks!
