FreeLists / si-list / [SI-LIST] HSPCIE Simulation about Transmission Line

[Zhangkun <zhang_kun@xxxxxxxxxx>]

Dear all
In the current simulation, I meet one problem. When there is short transmission 
line in the netlist, the simulation is very slow.

For example, in my netlist, there is the following sentence

wline_trunk01 node1      vss rseries1  vss rlgcfile=sline_50.rlgc n=1 l=1800mil
wline_trunk02 rseries2   vss stub_01   vss rlgcfile=sline_50.rlgc n=1 l=6500mil
wline_trunk03 stub_01    vss stub_02   vss rlgcfile=sline_50.rlgc n=1 l=200mil
wline_pull    stub_02    vss pull      vss rlgcfile=sline_50.rlgc n=1 l=200mil

wline_stub01 nd_out_01a vss nd_out_01 vss rlgcfile=sline_50.rlgc n=1 l=200mil
wline_stub02 nd_out_02a vss nd_out_02 vss rlgcfile=sline_50.rlgc n=1 l=200mil

If the length of the wline_stub02 is set as 10mil, the simulation would become 
very slow. Could anybody tell me the reason.

Best Regards
