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.
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
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
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...
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...
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.
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!
